  I bumped into this problem a while back.  In my case, it was caused
by building python with gcc and using another compiler for the C++
application.  You will find that __eprintf is found in libgcc.a.  This
library is usually buried a bit in the backwoods of a gcc install.  My
"fix" for this was just to extract out the object file which contained
__eprintf from libgcc.a and link it into our application.  There are
probably better ways of doing this.  In our case, we were able to use
gcc for building everything.  So, the problem went away that way :).
