 I've looked into this some more and found a large amount of reports with
 the same problem - no solution. The issue seems to that binaries compiled
 on 10.6 simply fail to load on 10.5 despite the correct SDK being used
 (10.4 in this case, I checked all individual files in the build log). I
 think this problem first started occurring when David C. upgraded his
 machine to Snow Leopard before 1.4.0.

 One of the most complete threads about this I found is
 http://web.archiveorange.com/archive/v/JT06FFoTBH5HKDgJ9T5X. At the end
 there is a report that including a compile flag {{{-mmacosx-version-
 min=10.4}}} helps. Will give that a try when I find the time.

 The only safe way to go though, as far as I can tell, is what Sage does:
 provide separate binaries for each version of OS X, built on that same OS
 version.
