Yes, you've run into a bug that I found and reported earlier
this year.  Here's my post and Torbjorn Granlund's reply:

I assume what's happened is what Torbjorn described:  a newer
libtool has arrived, the bug in libtool is still not fixed, and
so his temporary fix broke again.

I don't know how this sort of thing works in the free-software
world.  How do you get the libtoolers to undo their change
without getting involved in the development of libtool yourself?

Anyway, my own workaround was to invoke configure with CPPFLAGS=
-DDLL_EXPORT set.  That's the preprocessor define that libtool
is supposed to provide.
