It seems that in the Sage library code, the usage of some "Lfunction"
library from the lcalc package was newly introduced. On my Mac, both
the (half-built) Sage-4.5.2 and the older (fuly working) Sage-4.5.1
have under local/lib/ some library "libLfunction.so". But on a Mac
under OS X (OS X 10.4 at least), this would need to be
"libLfunction.dylib" to be usable ...

{{{
for the "Lfunction" issue, the relevant tickets are #5396 resp. #4793.
It seems to be as I thought --- the lcalc spkg (#4793) never built a
correct dynamic (".dylib") library on OS X. But this was not relevant
or did break anything, until the interface between Sage and lcalc was
changed from using pexpect to using this library directly (#5396,
introduced in Sage-4.5.2.alpha1).

Related: #4793, #5396.
