Date: Fri, 16 Dec 2011 10:41:08 -0600

So I don't forget:

Got a report of installed libtool failing on darwin because the libtool 
script being used was installed on a different device than the builddir, 
so ln "$progpath" "$lockfile" (for the lock for extracting an archive) 
will never work.

Need to:
1) Not lock on modern mac os x, ar no longer takes a lock on the archive 
when reading, this was fixed in Xcode-3.2.2.
2) Lock differently so that cross-device ln isn't involved.
