Oops, I have perl 5, version 36, subversion 3 (v5.36.3), with 'Keep' in the Full view Select Packages screen. I didn't see it in the Pending view, so thought I had the current perl. I must have downgraded at some point.

I didn't think about the problems packaging it that any maintainer who takes it on in the future would face. Perl on cygwin is a trouble-free experience using the system packages. I try not to install from CPAN, preferring a system package if it is available. I don't use cpanm, perlbrew or local::lib myself. When installing CPAN modules from the metacpan.org site, I do it with old-school cpan. > So, to summarize: App::cpanminus builds out of the box and passes its > own tests, but just like local::lib I don't want to distribute it as a > system package and /usr/local/ is left for whoever is in charge of that > system, not Cygwin upstream. I think that that's the right decision, a responsible one on your part. In view of my own old-school system-package-only conservatism, I'm not convinced I'm the right person to package cpanm either. But if we can't get Soren to package it, I guess I should think about doing it. > Here's the cygport file to produce a > system package if you want to play with that: > > --8<---------------cut here---------------start------------->8--- > # -*- mode: sh; sh-shell: bash -*- > BUILD_REQUIRES+=" libcrypt-devel" # perl.h > NAME="perl-App-cpanminus" > VERSION="1.7048" > RELEASE="1" > CPAN_AUTHOR="MIYAGAWA" > HOMEPAGE="https://metacpan.org/release/MIYAGAWA/App-cpanminus-1.7048"; > LICENSE="Artistic-1.0-Perl OR GPL-1.0-or-later" > DESCRIPTION="Perl distribution App-cpanminus, providing Perl modules: > App::cpanminus. > > Get, unpack, build and install modules from CPAN." > > [ "${CYGPORT_RPM_DIR:-no}" == "no" ] && [ -s "${PN}.src.patch" ] && > PATCH_URI+=" ${PN}.src.patch" > ARCH=noarch > DIFF_EXCLUDES="MYMETA.*" > > export PERL_NO_VENDOR_DEPS=1 > inherit perl > --8<---------------cut here---------------end--------------->8--- Thanks for the cygport file. That will help Soren or me get started. But we will probably need help uploading to the cygwin package repos. -- Greg "Dr Bean" Matheson Intention and action, night and http://drbean.sdf.org day.
