Hello,
Yum (2.1.12-0.fc3) doesn't like cyclic dependencies on packages to be
removed and fails.
Example:
# rpm -e mysql
error: Failed dependencies:
libmysqlclient.so.10 is needed by (installed) perl-DBD-MySQL-2.9003-5.i386
....
# rpm -e perl-DBD-MySQL
error: Failed dependencies:
perl-DBD-MySQL is needed by (installed) mysql-3.23.58-13.i386
# yum remove mysql
...

Also, yum remove ignores silently unknown packages passed as argument.
(And yum remove .... >& out outputs stderr before any stdout!)
