Back in December, 2004, Perl-Tk wouldn't run for me on an AMD64 system. After Googling and searching, I found a fix. With the most recent rpm's for Perl, Perl-Tk quit working for me again. This time it looks like there was a change to a filename from 'site-perl' to 'site_perl'. Anyway, here's what I did to fix it, this time: In .bashrc, I added the line export PERL5LIB=/usr/lib64/perl5/site_perl/5.8.0 and Perl-Tk started working again. The only difference from the December failure was using the underscore(_) in place of the dash(-). I did one other thing this time, too, and that was to get rid of the i386 version of Perl on my AMD64 machine using this command: yum remove perl.i386 Although I don't use Perl heavily now on AMD64 machines, I will be building several MythTV AMD64 boxes this year and they will need perl.x86_64 installed and working. Don't know if this will help you with your particular situation, but your description seemed like it might. Good luck. -- MM
