[Qgis-developer] Some errata on linux installations of qgis

[Tim Sutton]

Hi

You are using the CMAKE_INSTALL_PREFIX that points to the same dir as
where your sources are - is this intentional? Also the install
minifest error looks like a simple permissions error....

Martin would need to comment on the python issues.

Regards

Tim
