[pacman-dev] makepkg patch - simple pkg class feature

[Travis Willard]

I just wanted to throw this out there - this feature in general is
straying away from the simplicity of PKGBUILDs.

Can anyone give me a compelling reason why Dan's suggested
implementation of this feature is any better than just doing the
following:

build () {
    source $startdir/src/perl.build;

    pre_build();
    perl_build();
    post_build();
}

Which, to me, is a ton clearer about what exactly is going on than
some seemingly random variable in the sea of PKGBUILD options called
'buildlib=perl.build'.

It feels too much like featuritis, and hiding stuff from the users, in
any of the implementations suggested.
