[Qgis-developer] install instructions

[Barry Rowlingson]

Tried adding that PPA, now saga conflicts with itself in synaptic.

And if I install with apt-get it removes Qgis. If I try and install
Qgis, it removes Saga.

$ sudo apt-get install saga

currently says

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
 saga : Depends: libgdal1 (>= 1.8.0) but it is not going to be installed
        Depends: liblas1 but it is not going to be installed

trying to install libgdal1 results in qgis and a bunch of other
packages being REMOVED (in capitals) - I guess because they use
libgdal1h? Whatever that is.

I'm a bit disappointed that I've started from a clean, modern Ubuntu
install (ok, Mint) and am instantly in some kind of dependency hell. I
was hoping it would be "add a source, get qgis, get other goodies,
play".

 Does this all work off OSGeo Live 7?
