I was only looking for output from the building of one extension, not the
entire make.

Just curious, but how did you get the "-s" option set above.  Via
configure or did you edit your Makefile?

Here is your problem -- the "-DUSE_DL_IMPORT" option is missing above.
This means that somehow the value of CCSHARED got whacked in your
Makefile.  How did you accomplish this?  Please send me your Makefile.

If you do not specify the "-DUSE_DL_IMPORT" option during compilation,
then you will get error such as the above during linking.

Thanks,
Jason
