Well, it does not work when trying to install twisted because there is a definition like this missing: EXTRA_CPPFLAGS += -D_XPG4_2 > Running Twisted-13.1.0/setup.py -q bdist_egg --dist-dir > /tmp/easy_install-wDKJrR/Twisted-13.1.0/egg-dist-tmp-kZK7Ui > > twisted/python/sendmsg.c: In function 'sendmsg_sendmsg': > twisted/python/sendmsg.c:206:19: error: 'struct msghdr' has no member named > 'msg_control' > message_header.msg_control = NULL; > ^ > twisted/python/sendmsg.c:207:19: error: 'struct msghdr' has no member named > 'msg_controllen' > message_header.msg_controllen = 0; > ^ > > Here's how to install a specific version of a Python library: > http://stackoverflow.com/questions/5226311/installing-specific-package-versions-with-pip This is similar to the buildbot recommendation: http://docs.buildbot.net/current/tutorial/firstrun.html But unless there is a way to provide the extra flag it is of not much use. > If you insist on having a package, you could create an alternate > sqlalchemy package that would not install into /opt/csw/lib/pythonX.Y > but some custom place, specifically for buildbot.
