Hello Monks,

While installing the otherwise problem-free Cache::Cascade on a new Debian 4.0 system, I get this weird error from cpan:

  CPAN.pm: Going to build N/NU/NUFFIN/Cache-Cascade-0.01.tar.gz

I dived a bit into the test routines to see what's wrong, but I can't find the error. For testing, the t-script requires the module from the temporary path /root/.cpan/build/Cache-Cascade-0.01-3UluB4/blib/lib - where the module resides.
It should work but the test complains "Can't locate tt.pm in @INC" which isn't a module BUT a subroutine in Cascade.pm!

Any ideas?? A fresh look would help...
