[GRASS-dev] Crash in g.proj on Ubuntu

[Even Rouault]

Hi,

this is quite typical of a program linking to 2 different version of 
libproj at the same time, often when mixing repositories, where some 
components of one haven't been rebuilt against updated components of the 
other one

Check the output of "ldd /path/to/g.proj"
