[PyX-devel] Problems with lfs files when installed to non-standard location

[Fernando P. <Fer...@co...>]

Hi all,

I just installed PyX 0.6.2 on a clean system, but to a non-standard directory, 
using:

python setup.py install --home=~/usr/local

The installation went fine, and the lfs files (listed as data_files in 
setup.py) were correctly put in ~/usr/local/share/pyx.  However, in usage, PyX 
won't find any of them, and I get error messages like:

===========================================================================

---------------------------------------------------------------------------
IOError                                   Traceback (most recent call last)

I've been able to solve the problem by hand, by copying the contents of 
~/usr/local/share/pyx to ~/usr/local/lib/python/pyx/lfs.   But this seems like 
an ugly solution to me.  I don't know off-hand how to fix it, but somehow you 
guys will need to make the routine which searches for these files know where 
to look, even when the user installed to a different prefix.

Regards,

Fernando.

ps.  I'm loving pyx as it matures, keep up the good work!
