Yeah, that's basically what I'm trying now (still working on getting one of
the patches built correctly too). I was just hoping there was a way internal
to rpmbuild so I wouldn't have to run an external command, thinking that
would probably be cleaner.

Right now, I'm doing:
%define gnupg_version %(rpm -q --queryformat '%{version}' gnupg 2>/dev/null |
cut -d. -f 1,2)

Yup.

I like that idea, but in this case, the latest version doesn't need a patch.
If/when a future release of gnupg changes the output again that make this
patch necessary, then I'll create another set of entries to deal with the
current set of files for version 1.4.x, etc.

It does.
However, I'm getting an error trying to run rpmbuild against the spec file:
$ rpmbuild -ba perl-GnuPG-Interface.spec
error: syntax error while parsing ==
error: /home/lamontp/rpmbuild/SPECS/perl-GnuPG-Interface.spec:15:
parseExpressionBoolean returns -1
error: Package has no %description: perl-GnuPG-Interface
There is a %description (which works fine without this conditional stuff).
Lines 15 is:
%if "%gnupg_version" = "1.2"
I've double checked the exact command being used to define %gnupg_version and
that is working correctly. This makes me think that I've got a syntax error
on line 15, but it's such a simple line that I don't see what it could be.
If I take out line 15 (and corresponding elements), it works just fine, so it
really seems to be something wrong with the %if.
Any ideas?
BTW: I've already spoken with the package maintainer for this package (in
extras) and will be giving him the results of this for EPEL to be able to
build this package, too.
