Well, as I did not know the plan was to use gdal for GRASS, I sent my personal instructions which installed a second/third version in the home dir of the user.

So better to re-install/configure gdal so it will install it in the 'standard linux dirs' as Markus points to,

So instead of 

./configure --prefix=/home/richard/bin/gdal --with-ecw=/home/richard/bin/ecw5.5.0 

you will just do

./configure --with-ecw=/home/richard/bin/ecw5.5.0 

The --prefix part is the place where all stuff will be installed with the 'make install'.

If your own gdal is in /usr/local/bin, grass will 'just find it' (as that is one of the normal paths the compile tools will search for needed libs).

I think (plz correct me if I'm wrong) it i safest to de-install the distro's gdal first...

(and another option is in the GRASS compile step to explicitly point to the 'prefix-'-path of your own gdal)

Hope this make sense,
