The simplest general solution that I could derive that
works (barely) on all versions is the following:
---- snip ----
perl Makefile.PL `perl -MExtUtils::MakeMaker -e 'if ($ExtUtils::MakeMaker::VERSION =~ /5\.9[1-6]|6\.0[0-5]/) {print "PREFIX=/tmp/destdir/usr";}'`
make
make test
make install `perl -MExtUtils::MakeMaker -e 'if ($ExtUtils::MakeMaker::VERSION <= 6.05) {print "PREFIX=/tmp/destdir/usr";} else {print "DESTDIR=/tmp/destdir";}'`
---- snap ----
Axel was right. Since the source package should be
the same no matter what version of perl and the lines
to build the package must be contained within the
source, the detection must be within the spec file
itself. Otherwise you'll need different source
rpms for different versions of perl or MakeMaker,
which defeats the purpose of having one source rpm
for everything.
If there's a simpler solution, let me know. It
might simplify things to force an upgrade for those
with MakeMaker 5.91 .. 6.05, but we can't force
anyone to downgrade to an older version just so
we can have a static method to build the package.
Of course, once there exists such a version that
is both newer and supports the PREFIX= on the
"make install" line, we could simply widen the
range of "unsupported version" and hard code it
back to old PREFIX= method. Then just force
upgrade if within the range before building.
Other Ideas?
