[yt-users] Error on installation of yt on system python

[Nathan Goldbaum]

Hi Roberto,

Sorry my advice didn't help.  It's possible that reinstalling Cython will
fix the issue, although if you already have Cython 0.17.1 installed it's
probably fine as is.

One possible way around this would be to install yt using the install
script.  We've recently added the option to have the install script build
isolated LAPACK and BLAS installations which scipy can link against.  The
option is turned on by setting INST_SCIPY=1 in the install script.

Again, sorry I can't be of more assistance, I'm not sure what's going wrong
in your case.

-Nathan
