[QGIS-Developer] crssync issues

[Andreas Neumann]

Hi Even,

Yes - indeed that seems to be the case. There seem to be two versions of 
libproj on the system:

/usr/local/lib/libproj.so.19 and /usr/lib/x86_64-linux-gnu/libproj.so.15

The first was compiled by myself, the second seems have to be slipped in 
by the package manager.

And indeed spatialite seems to be the culprit - the only one that links 
to the old version.

Thanks a lot for your help!

Andreas
