Yes, I had added /usr/lib to my LDFLAGS environment variable. Before I
figured out that I needed the "-shared" flag, I was getting lots of undefined
references to things from posix libraries, etc. So I added references to c
libs. But then I came across a post that hinted at the "-shared" flag, and that
solved all the undefined references problems.
If in fact, the "-shared" flag is required, is there a mention of this
somewhere in the install instructions? It took me two days to figure
out what the problem was.
I was installing version 0.5.2.1. I have since gone on to install 0.6.0 on
another machine, and it seems as though this version didn't need the flag
(although I don't remmber exactly whether I may have in fact had it set). Did
anything change from the last version to this one? For some reason, I didn't
need this flag with numpy.
Thank you again,
