[yt-users] yt installaton failing

[Nathan Goldbaum]

Hi Agarwal,

Can you give us a little bit more detail on your setup - i.e. OS X version, intel or powerPC, and any other information that may be important.

The error you're seeing can happen when python is built on a 64 bit platform but tries to link against 32 bit libraries.  Can you try opening the python that install script built (it should be in $YT_DEST/bin/python2.7) typing 'import pyexpat'?.

I've never seen this error before so apologies for not having a quick solution.

Cheers,
