Tk doesn't work under RH9.

[nite_man]

Dear brothers and systers.

I had worked with Tk under Linux Red Hat 8.0 and life was nice. Than I've upgrated my Linux by Red Hat 9 and as result, I cannot install correctly (make test returns error 2) Tk for Perl but if I nevertheless install it when I try to run a symple script which produces only one window with button, I have error:

'6x13*font:' isn't numeric at
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Tk/Widget.pm
line 188.

I've found some topics about this error in the internet forums. Authors those topics suggest set LANG in 'en_US' instead of 'en_US.UTF-8' as set defaul in RH9. But I still cannot use Tk. I have exactly the same error.

Any suggestions will be useful.

My environment: Red Hat 9, Perl 5.8.0 built for i386-linux-thread-multi, Tk 800.025.

Thanks in advanced,
