description:
Pass down PKGVERSION_NOREV in another spot to avoid another PLIST

previous version of this package installed.

+On systems where both of the conditions
+
+1. LD_LIBRARY_PATH does _not_ take precedence over DT_RPATH
+   (e.g. Linux)
+2. A previous libpython with the same major.minor is already installed
+   (e.g. a previous version of this package)
+
+hold, the built python will be linked with the installed libpython,
+causing it to report an old teeny version in
+self.distribution.get_version() while staging the install. Then "make
+package" fails with PLIST mismatches for Python-2.7.XX-py2.7.egg-info.
+
+pkgsrc knows which version we're building. Pass that down instead.
+
+In patch-Lib_distutils_unixccompiler.py, we override Python maintainers'
+expectations for Linux builds in favor of pkgsrc's expectations for
+builds on all platforms. This patch is needed because of that patch.
