I could not build SFCGAL on RHEL 6, due to boost issues, which you also
encountered.

Other than that, we don't use any toolchain which is not included in
the repo. If we make an exception, we add it to our repo.
$ rpm -qv rpm-build
rpm-build-4.8.0-47.el6.x86_64

Err, actually it is the new %license macro that was introduced
recently, and I forgot to add conditionals. See line 50 in here as an
example of what I missed:

As above: We all stick to OS supplied packages, so:
$ rpm -qv boost-devel
boost-devel-1.41.0-27.el6.x86_64
We also use EPEL repo a lot.

Yep, I got the same.

We don't do it, as it will break more dependencies. For the same
reason, we disabled raster support on RHEL 6 RPMs.
