I *assume* that perldoc is looking for an executable "perl" in the path (call perldoc with option -v) and finds - reported by Cygwin - perl.exe. Opening "perl" obviously fails then in function "containspod" of perldoc. You can recreate the problem with any other perl.pod topic by creating a appropriate executable, e.g. just copy /bin/perldoc to /bin/perlintro.exe and call "perldoc perlintro". As workaround call perl.pod with extension (as your recommendatiuon above) or delete /bin/perl.exe and create a link from /bin/perl5.8.0.exe to /bin/perl.

This should do it.

This too.

It should find perl.pod in the @INC, but it doesn't, instead it looks
in /bin and finds the executable.

No problem, that was the same what I saw, I fiddled around at some
lines and tried to change this and that, but it became worse and I
decided to let it as it is until some nice guy comes up with a nice
bug report which helps us to track it down :-)

Gerrit,
I'm by no means a perl guru, but here are a few observations from
/usr/bin/perldoc:
266: sub searchfor {
267: my($recurse,$s,@dirs) = @_;
276: for ($i=0; $i<@dirs; $i++) {
277: $dir = $dirs[$i];
279: if ( ( $ret = check_file $dir,"$s.pod")
280:or ( $ret = check_file $dir,"$s.pm")
281:or ( $ret = check_file $dir,$s)
... etc ...
312: }
400: foreach (@pages) {
413: # We must look both in @INC for library modules and in $bindir
414: # for executables, like h2xs or perldoc itself.
415: my @searchdirs = (@INC, $bindir);
434: my @files = searchfor(0,$_,@searchdirs);
462: }
In other words, it looks like the script searches @INC (which can vary
from version to version). If you look at the changes in @INC between
5.6.1 and 5.8, you could probably track down this problem.
Sorry if I'm restating the obvious.
Igor

Yes, please fix it :-) I just figured that calling: perldoc perl.pod works well. I tried to understand what happens in the perldoc script and I have no idea why it doesn't work. And most interesting is that it works with perl 5.6.1.
