Tix install question

[Eric Texier]

I am trying to install Tix on a linux machine. I don't have access
privilege to write above my user directory.
There is already a python1.5 on the machine.
I installed  tcl8.3, tk8.3, tix8.1 and python2.2 with  --prefix =
/usr/people/erict/bin
It was 'succefull'
I included the following line in my .cshrc:
setenv PYTHONHOME /usr/people/erict/bin
setenv PYTHONPATH /usr/people/erict/bin/lib
setenv TIX_LIBRARY /usr/people/erict/bin/lib
setenv TCL_LIBRARY /usr/people/erict/bin/lib
setenv TK_LIBRARY /usr/people/erict/bin/lib

now here what I am getting:
erict_fairlop > python
Python 2.2.1 (#3, Apr 25 2002, 15:25:49)
[GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tix
>>> root = Tix.Tk()
/usr/people/erict/bin/lib/libtix8.1.8.3.so     ## print out that I had
to see what it was trying to load
Traceback (most recent call last):

    self.tk.eval('package require Tix')
TclError: couldn't load file "/usr/lib/libtix": /usr/lib/libtix.so:

Any Idea
Thanks
