[Qgis-developer] Cannot load python after compiling master

[Mikhail Tchernychev]

I was able to fix it by defining LD_LIBRARY_PATH to point to development 
libs.

like export LD_LIBRARY_PATH=/home/misha/opt/qgis-dev/lib

Aparently there qgis tries to load  libs from other places; in my case 
it is probably
because I have qgis installed from repository.
