Error starting opera 8.00

[Frank Staals]

Hey,

I downloaded opera 8.00, extracted the .tar.gz and ran the install.sh 
script, all the files were copied to the right places. When I tried to 
run opera I first had to symlink 2 libs ( libm.so.2 and libc_r.so.4 ) 
that wasn't much of a problem but when I try to run it now I get this 
error:

frank at Riza$ opera
/usr/libexec/ld-elf.so.1: /usr/X11R6/lib/libX11.so.6: Undefined symbol 
"__stderrp"

I am running FreeBSD 5.3.

Anyone an Idea what I am doing wrong ?

Thanks Frank
