Oracle Database Discussions

I've run Opatch a million times before (well, maybe not that many but quite a few anyways). Now I'm trying to run it again and I get the following message:

"OPatch could not detect Perl.
Please set PERL5LIB appropriately and invoke Perl."

I even installed Active Perl, in case there was something missing, to no avail.

I'm using Windows 2000 Professional.
This is what my variables looks like:

PERL5LIB=C:\Perl\lib;C:\Oracle\product\10.1.0\db_1\perl\5.6.1\lib
PATH=C:\Oracle\product\10.1.0\db_1\perl\5.6.1\bin\MSWin32-x86;C:\Perl\bin\

If I do a perl -v from the command line, I get the following:
------------------
This is perl, v5.8.7 built for MSWin32-x86-multi-thread
(with 14 registered patches, see perl -V for more detail)

So perl is responding, but opatch doesn't see it for some reason. What am I missing?

Thanks!
