Sorry forgot to attach: Hi, Two things: 1. I can't get yt-1.5 to finish installing. Hangs with the numpy pkg: build/temp.linux-i686-2.6/numpy/linalg/lapack_litemodule.o:/ ... more undefined references to `PyType_IsSubtype\ follow ... python_xerbla.c:35: undefined reference to `PyErr_SetString' ... collect2: ld returned 1 exit status -L/usr/lib/llapack -lblas -lg2c -o build/lib.linux-i686-2.6/numpy/linalg/lapack_lite.so" failed with exit status 1 2. The old yt I've been using never did install "iyt" though "yt" has worked fine. (it's not in the bin) I attached a coupled of ref's might be helpful. Thanks for yout time.
