ActiveState Perl, cygwin and R (was: cygwin tar?)

Hello! I have just read mails in thread <http://tolstoy.newcastle.edu.au/R/devel/04a/0583.html> about problems with Cygwin and Rtools. I had the same problems and kept just the newest cygwin1.dll and things seem OK now. However I currently hit the problem with Perl (I have ActiveState and Cygwin Perl installed). When I tried to work with 'Rdconv' in Cygwin I get the following: $ R CMD Rdconv --help Can't locate R/Rdconv.pm in @INC (@INC contains: c \Programs\R\rw2011beta\share\perl; /usr/lib/perl5/5.8/cygwin /usr/lib/perl5/5.8 /usr/lib/perl5/site_perl/5.8/cygwin /usr/lib/perl5/site_perl/5.8 /usr/lib/perl5/site_perl/5.8 /usr/lib/perl5/vendor_perl/5.8/cygwin /usr/lib/perl5/vendor_perl/5.8 /usr/lib/perl5/vendor_perl/5.8 .) at c:\Programs\R\rw2011beta/bin/Rdconv line 25. BEGIN failed--compilation aborted at c:\Programs\R\rw2011beta/bin/Rdconv line 25. As far as I understand there is a problem since Cygwins perl does not have things properly setup. I did not touch anything yet. But I can see the problem in first entry of @INC. There should be /cygdrive/c/.. or c:/ (I do not know if the last one actually works with Cygwins perl) and therefore things are broken.
The problem is earlier: the path separator is ; on Windows and : on Cygwin.
If I modified PATH such that ActiveState Perl was before Cygwins Perl, everyting was as expected. Is there a way to overcome this with Cygwins Perl?
No. It is very clearly documented that a Windows Perl is required.
