When I try to make custom package of Python 2.7, I use the spec file attached in /Misc/RPM. I don't really use it to build Python as I want to define some specific options, but I do use it as a source of RPM package meta data which I can simply reuse when creating the final RPM, e.g.:

rpm -q --specfile ./Misc/RPM/python-2.7.spec --queryformat '%{DESCRIPTION}'

Manipulation with that specfile in RPM 4.4.2.3 (CentOS 5.6) is fine, but there are warnings in RPM 4.8.0 (CentOS 6.5):

warning: line 71: buildprereq is deprecated: BuildPrereq: expat-devel
warning: line 72: buildprereq is deprecated: BuildPrereq: db4-devel
warning: line 73: buildprereq is deprecated: BuildPrereq: gdbm-devel
warning: line 74: buildprereq is deprecated: BuildPrereq: sqlite-devel
warning: line 91: prereq is deprecated: Prereq: python2.6 = %{PACKAGE_VERSION}
warning: line 122: prereq is deprecated: Prereq: python2.6 = %{PACKAGE_VERSION}-1pydotorg

Here's related thread: https://groups.google.com/forum/#!topic/comp.lang.python/R8ahiZ5wyhc
and most importantly here's proof/explanation: http://www.rpm.org/wiki/Releases/4.8.0#Packagebuilding

• PreReq and BuildPreReq are now officially deprecated, with warnings at build-time
• PreReq is mapped to Requires(pre,preun) at build-time

Requires(pre,preun) is backwards compatible, so it works in RPM 4.4 too, I would therefore suggest to change "[Build]Prereq" to "[Build]Requires(pre,preun)" respectively in the specfile to reflect this.

I'm happy to send a patch if some maintainers will agree with proposed solution.

We just deleted the spec file.
