[El] RHEL5: Problem with Qgis 1.6.0 and some python-dependant plugins

[Mauricio Zambrano]

Dear list,

While trying to install the '1-band raster Colour Table v1.x' plugin for
Qgis 1.6.0, I got the following error message:


"You need to install the following python module in order to enable it:
numpy"

but I already had the 'numpy' library installed on my system, along with
both python 2.4 and python 2.6.

This problem is reported, with as much detail as I could, in the
following thread:

http://forum.qgis.org/viewtopic.php?f=5&t=8214.


About my Qgis version:

After a while, I realised that the real problem was that some Qgis
plugins only detect python 2.4 and its associated libraries.

For example, this morning the IT manager of my unit installed numpy for
the python2.6 version of my system (at that moment I realised that numpy
needs to be installed for each python version present in the system),
and the numpy error message (at the beginning of this e-mail)
disappeared. 

However, I got this new error message:

"You need to install the following python module in order to enable it:
osgeo"

and in another thread
(http://www.osgeo.org/pipermail/gdal-dev/2008-August/017923.html)
somebody guessed that the problem was that the "path where gdal library
was installed is not available to loader"

and suggested trying this:

export LD_LIBRARY_PATH=/usr/lib/libgdal.so


I tried it, but I'm still getting the same error. 

Here is the messages that I got form the console while launching Qgis:

I would really appreciate any help about how to make Qgis may install the 
'1-band raster Colour Table v1.x' plugin, or how to make that Qgis may detect 
the gdal version of my system.

Thanks in advance,

Mauricio
