   <P>
   I believe (but am not 100% confident) that the following
   RPMs are necessary (in addition to the current ones
   in rpm_list.txt) to run MySQL.  Basically I discovered these
   dependencies while trying to do external RPM based installs.
   I assume, and sometimes found, that these dependencies apply
   to tarball-based distributions too.  (So to play it on the
   safe side, I am going to include these RPMs as part of the
   core, minimal RPM set.)

   Note: the mysql site recommends that Linux users install by
   using the MySQL RPMs (MySQL-client, MySQL, MySQL-shared, etc).
   While these RPMs work, I was unsuccessful at integrating
   this RPM-installed database with perl modules from www.cpan.org.
   Hence, I <STRONG>strongly</STRONG> recommend that, when installing
   from "source", MySQL and the perl components be in fact installed
   from their tarballs (.tar.gz, .tgz).  (Perl components, when installed
   from RPMs, also wound up in incorrect locations on the disk.)
   Do not coordinate a source install with externally made RPMs!
   It is, of course, okay to use LON-CAPA RPMs such as LON-CAPA-systemperl
   and LON-CAPA-mysql since we, in fact, made these RPMs correctly :).

   <P>So, here is exactly how I installed MySQL-3.23. (Note that all files
   wind up in /usr/local/mysql-3.23.33-pc-linux-gnu-i686 except for
   a link from /usr/local/mysql to /usr/local/mysql-3.23.33-pc-linux-gnu-i686
   and some files involved in system process handling (/etc/rc.d/*/*mysql).
   </P>
   <P>This is how I installed the Msql-Mysql-modules perl modules.

   [root@fenchurch Msql-Mysql-modules-1.2215]# perl Makefile.PL 
   Which drivers do you want to install?
   
       1) MySQL only
       2) mSQL only (either of mSQL 1 or mSQL 2)
       3)  MySQL and mSQL (either of mSQL 1 or mSQL 2)
   
       4)  mSQL 1 and mSQL 2
       5)  MySQL, mSQL 1 and mSQL 2
   
   Enter the appropriate number:  [3] 1
   
   
   Do you want to install the MysqlPerl emulation? You might keep your old
   Mysql module (to be distinguished from DBD::mysql!) if you are concerned
   about compatibility to existing applications! [y] n

   This is how I installed the DBI perl modules.
   <PRE>
   [root@fenchurch DBI-1.14]# perl Makefile.PL
   *** Note:
       The optional PlRPC-modules (RPC::PlServer etc) are not installed.
       If you want to use the DBD::Proxy driver and DBI::ProxyServer
       modules, then you'll need to install the RPC::PlServer, RPC::PlClient,
       Storable and Net::Daemon modules. The CPAN Bundle::DBI may help you.
       You can install them any time after installing the DBI.
       You do *not* need these modules for typical DBI usage.
   
   Optional modules are available from any CPAN mirror, in particular
       http://www.perl.com/CPAN/modules/by-module
       http://www.perl.org/CPAN/modules/by-module
       ftp://ftp.funet.fi/pub/languages/perl/CPAN/modules/by-module
   
   Checking if your kit is complete...
   Looks good
   Writing Makefile for DBI
   
       Remember to actually *read* the README file!
       Use  'make' to build the software (dmake or nmake on Windows).
       Then 'make test' to execute self tests.
       Then 'make install' to install the DBI and then delete this working
       directory before unpacking and building any DBD::* drivers.
