It seems that the libnumarray.so (which your extension is probably
trying to load) is not in a directory where your system will like
loading it from.  It's hard to say more without knowing about your
system, and the way you've set things up for it in terms of loading of
dynamic libraries (which IS a very system-dependent thing).
