I think I've fixed this particular case, but the problem in general
needs more work, so the compile may simply fail on a later module or
library.   Make sure you have run ./configure recently, as if you have
not done this for a number of weeks, it may be using a particular linker
flag that I've temporarily disabled.

I hope this helps,
