Cygwin 1.7 perl build problems.

Hello. I am using the Cygwin 1.7 (beta) environment. Within Cygwin, there is a version of perl 5.10.0.

I fetch the Tk module source, extract it, cd into the Tk-804.028 directory and type the following:

$ perl Makefile.PL
Cannot find '/usr/lib/perl5/5.10/i686-cygwin/CORE/perl.h' have you installed /usr/bin/perl?
Compilation failed in require at Makefile.PL line 37.
BEGIN failed--compilation aborted at Makefile.PL line 39.

lwv27@PC89067 ~/.cpan/build/Tk-804.028-n8BLky
$ ls '/usr/lib/perl5/5.10/i686-cygwin/CORE/perl.h'
/usr/lib/perl5/5.10/i686-cygwin/CORE/perl.h

Is this a problem that anyone recognizes and has identified a solution?

I checked the Makefile.PL file, and it has normal Cygwin line endings.

I have tried one other install - that of a newer version of the CPAN module, used to fetch source from the perl community module repository.
It too fails, but in a rather more peculiar manner:
$ /bin/perl Makefile.PL
Unable to find a perl 5 (by these names: /usr/bin/perl.exe perl.exe perl5.exe perl5.10.0.exe miniperl.exe, in these dirs: /home/lwv27/bin /usr/local/bin /usr/bin /bin /usr/X11R6/bin /cygdrive/c/Program Files/Perl/bin/ /cygdrive/c/NTSA/Bin /cygdrive/c/NTSA/4NT /cygdrive/c/Program Files/Activestate Tcl/8.4.10.1/bin/ /cygdrive/c/WINDOWS/system32 /cygdrive/c/WINDOWS /cygdrive/c/WINDOWS/System32/Wbem /cygdrive/c/i386 /cygdrive/c/Program Files/ATI Technologies/ATI.ACE/ /cygdrive/c/NTSA/Bin/ /cygdrive/c/Program Files/Rational/common /cygdrive/c/Program Files/Rational/ClearCase/bin /cygdrive/c/casnc/oracle/product/10.2.0/client_1/BIN/ /cygdrive/c/Program Files/Hummingbird/Connectivity/Accessories/ /cygdrive/c/Program Files/QuickTime/QTSystem/ /cygdrive/c/Program Files/Intel/DMIX /cygdrive/c/Products/apache-maven-2.2.1/bin /usr/local/bin /usr/bin)

$ /bin/perl --version

This is perl, v5.10.0 built for cygwin-thread-multi-64int
(with 6 registered patches, see perl -V for more detail)

So in one case, perl says it cannot find itself, and in the other case, perl says it cannot find one of its headers that is present.

I posted the attached patch for Tk-804.028 in February 2008 to this list
to build Tk under cygwin. I believe the svn version at
https://svn.perl.org/modules/Tk/trunk has this already.

It builds fine, but there's still a known problem with the
unix-eventhandler. I'll fix that when I have time.

Thank you very much. I wonder if the community around that module have just stopped producing new releases. Perhaps that would explain why a patch provided 21 months ago isn't in CPAN yet.

Have you encountered the other problem I mentioned, where saying

perl Makefile.PL

will, in some cases (like Text::CSV) result in a message saying that no perl 5 could be found? The only perl in Cygwin is a perl 5, so the message seems rather strange.
