I installed the latest MySQL and perl-DBD-MySQL from Rawhide. These
place files in /etc/ld.so.conf.d containing "/usr/lib/mysql". However,
libraries in that directory are not subsequently added to the cache,
as revealed by "ldconfig -v". Running ldd against the mysql.so from
perl-DBD-MySQL shows that it can't find libmysqlclient.so.14. I
strace'd ldconfig and found that it never referenced /etc/ld.so.conf.d.
If I run ldconfig with /usr/lib/mysql included on the command line, my
Perl scripts (and in particular, my bugzilla installation) work again.
is in your /etc/ld.so.conf
Guess you haven't merged /etc/ld.so.conf.rpmnew with /etc/ld.so.conf during
FC3 glibc edits this file automatically, but FC2 does not.
Anyway, during any install you should scan .rpmnew files and check what
needs updating always, otherwise you can end up with not fully functioning system.
