Log message:
python: egg.mk: add USE_PKG_RESOURCES flag

This flag should be set for packages that import pkg_resources
and thus need setuptools after the build step.

Set this flag for packages that need it and bump PKGREVISION.

Log message:
*: bump PKGREVISION for egg.mk users

They now have a tool dependency on py-setuptools instead of a DEPENDS

Log message:
py-cymruwhois: py-nose is a test dependency, not build

Log message:

Log message:
py-cymruwhois: update to 1.6

Changes 1.6:
Add in a check for the windows version of EWOULDBLOCK
Apparently in newer versions of python this just works, but in older
versions the error codes were not consistent across platforms.

Log message:
Use "${MV} || ${TRUE}" and "${RM} -f" consistently in \ 
post-install targets.

Log message:
Remove unnecessary PLIST_SUBST and FILES_SUBST that are now provided
by the infrastructure.

Mark a couple more packages as not ready for python-3.x.
