Ok. I think I figured out most of the dependency issues. Two problms still:

1)
$ make
make: "../../lang/python/../../lang/python/extension.mk" line 25: warning: duplicate script for target "do-build" ignored
make: "../../lang/python/../../lang/python/extension.mk" line 25: warning: using previous script for "do-build" defined here
make: "../../lang/python/../../lang/python/extension.mk" line 29: warning: duplicate script for target "do-install" ignored
make: "../../lang/python/../../lang/python/extension.mk" line 29: warning: using previous script for "do-install" defined here
make: "../../lang/python/../../lang/python/extension.mk" line 25: warning: duplicate script for target "do-build" ignored

make: "../../lang/python/../../lang/python/extension.mk" line 29: warning: using previous script for "do-install" defined here

I don't understand what is going on here

2) I don't understand how the build is generating this error:

It was building yesterday when I wasn't just using buildlink includes
for determining dependencies.

I'll email you the two needed sharfile packages for this off list.
Thanks for the assistance.
