[yt-users] Installing yt within Enzo 1.5

Hi, Enzo 1.5 works fine but yt won't install from within it (enzo/src/yt). It hangs at numpy. I've installed yt before but had to hand install several other things for wxPython, for gtk++ etc. Is the yt included in this installation any different then? Thanks for your time. R.Soares
