[PyFeyn] I cannot install the package

[Rebeca Gonzalez Suarez]

Hi,
I'm trying to install pyFeyn in my computer (Mac OS X 10.6.7) and I get 
the following error message:

----------------------------------------------------
Running PyX-0.10/setup.py -q bdist_egg --dist-dir 
/tmp/easy_install-DNzGcZ/PyX-0.10/egg-dist-tmp-oh9bOA
error: Setup script exited with error: SandboxViolation: 
mkdir('/System/Library/Frameworks/Python.framework/Versions/2.6/share',) {}

The package setup script has attempted to modify files on your system
that are not within the EasyInstall build area, and has been aborted.

This package cannot be safely installed by EasyInstall, and may not
support alternate installation locations even if you run its setup
script by hand.  Please inform the package's author and the EasyInstall
maintainers to find out if a fix or workaround is available.
----------------------------------------------------

So I'm sending it to you. Is it possible to fix it?
Many thanks in advance,
Cheers,

Rebeca
