Sorry. I'm having problems getting Devel::Cover to install on Strawberry Perl right now.

dmake.EXE: makefile:  line 1113:  Error: -- A non AUGMAKE meta target 
+must not be mixed with AUGMAKE meta targets, offending target [BUGS]
PJCJ/Devel-Cover-0.65.tar.gz

Sorry, I wish I had more time to check it out.

Good luck!
