Thanks for the info, I appreciate it. I had a heck of a time getting
database/py-sqlite3 to build as well. 
My workaround to get it installed was to change the Makefile in WRKSRC

try:
import ctypes
ctypes.CDLL('libsqlite3.so').sqlite3_load_extension
except AttributeError:
macros.append(('SQLITE_OMIT_LOAD_EXTENSION', '1'))

it was bombing out on the 'except AttributeError:' line. 
So I just changed it to 

macros.append(('SQLITE_OMIT_LOAD_EXTENSION', '1'))

since I didn't have the extensions option SQLITE, if you have that option then
just delete the whole block, nothing needed.
Of course the 'better' way is to find the source of the issue. :)
