Did you try setting the CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH environment 
variables ? This should help.

What la files ? On Linux they are only text files. There must be also "real" 
libraries available.

So libagg needs libresolv ? For which functions ?

Ranger Rick, Tanner, what do you think about the following issues ?

This one is already in svn.

You're very welcome :-)
A good thing would be if you could setup a nightly build on your machine. 
Basically this means creating a cron job which executes "make Nightly" once 
per day.
The results will go here:
