(Still waiting for bugzilla password to arrive - will paste this into
the bug when it does).

I have had other reports of this, and changed libtool in 1.5.26 and HEAD
to use ld's  -exported_symbols_list flag if it is available, instead of
a separate invocation of nmedit. In one case this fixed the problem.

I have not had time to reproduce on my own system to gather enough
information to file a bug with Apple - a trivial test case I tried a
month or two ago worked fine with nmedit being used to limit the
exported symbols.

I will try to find the time to investigate, in the meantime, either
remove the exported symbol limiting on darwin (ugh.) or try with latest
