Greg' Ar,

I'm not an SBo package maintainer but I offer a thought I learned a long
time ago about the build sequence for spatial analyses packages. Perhaps
it's relavent to your question, perhaps not.

The stack proj -> geos -> gdal need to be built in that order. If proj is
updated then the other two must also be upgraded. If geos is upgraded then
gdal has to be rebuilt. Any other software depending on those need the stack
to be rebuilt before they are.

I've found this is needed with GRASS, R, and SAGA.

Rich
