Comment 37 for bug 254035

Okay, the Tahoe setup.py now has a couple of work-arounds for this issue on two platforms:

http://allmydata.org/trac/tahoe/browser/setup.py?rev=20080924174255-80e44-63903e9efb0c9b8a6f58cedfbc96ecb6f352837a#L15

15 basedir = os.path.dirname(os.path.abspath(__file__))
16 pyver = "python%d.%d" % (sys.version_info[:2])
17 if sys.platform == "win32":
18 supportlib = os.path.join("support", "Lib", "site-packages")
19 else:
20 supportlib = os.path.join("support", "lib", pyver, "site-packages")
21 supportlib = os.path.join(basedir, supportlib)

Presumably we'll add similar kludges when this problem crops up on other platforms. :-/
