Linux problem? - realplay and acroread die

[David Banning]

All of a sudden I have both linux-realplayer -and- acroread7 die.

realplayer ends with a "Segmentation fault: 11 (core dumped)" and 
acroread just dies without a message.

I have done redone my ports using portsnap, and used portupgrade 
to reinstall both programs. I have also reinstalled linux_base using
"portupgrade -f -R linux_base*"

I expect that the problem is linux related as both programs appear to be
linux programs.

No solution as yet and I am at my wits end! - Wondering if anyone has
a suggestion -

I am using freebsd 6.2 Release
