Lionel,

How have you installed the application ?

osgeo.gdal is the new way to import gdal python, I don't know if TC try to 
import gdal using the old way.

see http://pypi.python.org/pypi/GDAL/ USAGE section:
********* quote begin *******
Imports

There are five major modules that are included with the GDAL Python bindings.:

>>> from osgeo import gdal
>>> from osgeo import ogr
>>> from osgeo import osr
>>> from osgeo import gdal_array
>>> from osgeo import gdalconst

Additionally, there are five compatibility modules that are included but 
provide notices to state that they are deprecated and will be going away. If 
you are using GDAL 1.5 bindings, you should update your imports to utilize 
the usage above, but the following will work until at least GDAL 2.0.

>>> import gdal
>>> import ogr
>>> import osr
>>> import gdalnumeric
>>> import gdalconst

If you have previous code that imported the global module and still need to 
support the old import, a simple try...except import can silence the 
deprecation warning and keep things named essentially the same as before:

>>> try:
...     from osgeo import gdal
... except ImportError:
...     import gdal
********* end of quote *******

regards,

Y.
