I am running bash and this is what I get for PATH

Ok - thanks. Can you show us the results of running the following commands. (For reference, I'll also show what I get.) 
Rob@desktop2 ~
$ which perl
/usr/bin/perl

Rob@desktop2 ~
$ which gcc
/usr/bin/gcc

Rob@desktop2 ~
$ which make
/usr/bin/make

Rob@desktop2 ~
$ perl -e 'print $^X'
/usr/bin/perl.exe

Rob@desktop2 ~
$ perl -V:make
make='make';

Rob@desktop2 ~
$ perl -V:cc
cc='gcc';

Rob@desktop2 ~
$ perl -v

You should be getting essentially the same.

Who built the Perl in C:/Perl/bin ? If it's ActiveState perl then you should be building stuff for it in the cmd.exe shell using either mingw (which I see you have) or a Microsoft compiler. It would be rather tricky and somewhat unusual to be building extensions PDL for ActivePerl inside the Cygwin environemnt. If you want PDL to run with ActivePerl perl, it should build easily in the cmd.exe shell using mingw - or you can just ppm install PDL from http://cpan.uwinnipeg.ca/PPMPackages/10xx (perl-5.10) or http://theoryx5.uwinnipeg.ca/ppms/ (perl-5.8).

Cheers,
Rob
