Sorry, I didn't mean to sound dismissive. Perhaps I misunderstood what 
"these" actually referred to. The results of omitting these flags 
specifically:

      "-lpython2.5 -lpthread -lm -lutil -ldl -shared"

Are posted here for both numpy and scipy:

I have not tried unsetenv'ing $LDFLAGS entirely, an option which did not 
occur to me given their necessity for just about everything else. If you 
think that this is a worthwhile experiment, I will run it.

I think I would like to know how to avoid or correct these sort of 
issues in the future, which seem to be limited, for me at least, to 
scipy and numpy, with the possible exception of MySQLdb and its 
dependency on zlib. Ideally, I would like to understand exactly what 
causes these errors in addition to knowing what I can do to correct them 
in the future.
