I'm having trouble building rgeos from source under linux. I have R-2.15.1,
and rgeos 0.2-7, it appears to build ok, but fails the final install check:

Thanks Barry for your interest in my problem. It is indeed an interesting
problem at the same time as a complex one.
I've tried your code and it works for two lakes so far. It's seems like a very
good base for what I want to do. I'll modify it a little to speed it up.
First by removing the

Dear all,
My aim is to test the robustness of a regression that has a dummy for a set
of contiguous (rook) polygons.
I need to generate random sets of pseudo-regions, i.e. contiguous polygons
randomly selected, and then check if the regression results are robust.
I would like to create this pseudo

Dear R gurus,
I'm facing a challenge that I have a good feeling you could help me with. So
far I'm stuck right at the beginning so I don't have any example to show you.
Here is what I'm trying to do:
I have a polygon shape of lakes for which I have to be able to automatically
determine if th
