Replace the perl/Makefile.PL and the fallback perl/Makefile used under NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily inspired by how the i18n infrastructure's build process works[1]. The reason for having the Makefile.PL in the first place is that it was initially[2] building a perl C binding to interface with libgit, this functionality, that was removed[3] before Git.pm ever made it to the master branch. We've since since started maintaining a fallback perl/Makefile, as MakeMaker wouldn't work on some platforms[4]. That's just the tip of the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to detect whether we need to regenerate the perl/perl.mak, which I fixed just recently to deal with issues like the perl version changing from under us[6]. There is absolutely no reason for why this needs to be so complex anymore. All we're getting out of this elaborate Rube Goldberg machine was copying perl/* to perl/blib/* as we do a string-replacement on the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as pod2man-ing Git.pm & friends. So replace the whole thing with something that's pretty much a copy of how we generate po/build/**.mo from po/*.po, just with a small sed(1) command instead of msgfmt. As that's being done rename the files from *.pm to *.pmc just to indicate that they're generated (see "perldoc -f require"). While I'm at it, change the fallback for Error.pm from being something where we'll ship our own Error.pm if one doesn't exist at build time to one where we just use a Git::Error wrapper that'll always prefer the system-wide Error.pm, only falling back to our own copy if it really doesn't exist at runtime. It's now shipped as Git::FromCPAN::Error, making it easy to add other modules to Git::FromCPAN::* in the future if that's needed. Functional changes: * This will not always install into perl's idea of its global "installsitelib". This only potentially matters for packagers that need to expose Git.pm for non-git use, and as explained in the INSTALL file there's a trivial workaround. * The scripts themselves will 'use lib' the target directory, but if INSTLIBDIR is set it overrides it. It doesn't have to be this way, it could be set in addition to INSTLIBDIR, but my reading of [7] is that this is the desired behavior. * We don't build man pages for all of the perl modules as we used to, only Git(3pm). As discussed on-list[8] that we were building installed manpages for purely internal APIs like Git::I18N or private-Error.pm was always a bug anyway, and all the Git::SVN::* ones say they're internal APIs. There are apparently external users of Git.pm, but I don't expect there to be any of the others. As a side-effect of these general changes the perl documentation now only installed by install-{doc,man}, not a mere "install" as before. 1.5e9637c629
