Okay, this is interesting.  I got rid of /usr/bin/perl, and copied 
perl5.8.5.exe back to perl.exe.  Then I tried the exact sequence you had 
below and it worked.  For some reason the /usr/bin/perl1 soft link works 
but the /usr/bin/perl soft link does not.  I'm at a loss.  Why can't I 
make /usr/bin/perl a soft link to /usr/bin/perl5.8.5?  Why does this 
only seem to affect certain systems?

Thanks,
IF
