Question about the toolchain (CGAL / SFCGAL related)

Hello,

I'm having a bit of trouble building SFCGAL / CGAL, and I wanted to ask a
couple of questions about the toolchain used to build the code.
Specifically, I was wondering about builds on EL-6.

1) For EL-6 builds, what version of rpmbuild is installed (and how is it
installed)?
The latest version I found via yum install is 4.8.
With the spec-file as written, I encounter the following build errors on
SFCGAL:

File must begin with "/": GLPLv2
File must begin with "/": LICENSE

From my research, this happens because non-absolute paths were added
in RPM 4.11. So, the 4.8 standard install causes problems.

2) For EL-6 builds, what version of boost-devel is installed (and how
is it installed)?

It seems like Boost is a tricky thing on EL-6. The latest RPM that is
available for installation is 1.41.0. However, without a later
version, there's a compile error on CGAL 4.7:

/usr/include/CGAL/Kd_tree.h:34:37: fatal error:
boost/container/deque.hpp: No such file or directory

From what I gather, deque.hpp has been relocated elsewhere in code for
later versions of boost. And, while there is a boost148 package
available, it unfortunately puts the Boost include files into
/usr/include/boost148 instead of /usr/include/boost. Unless there's a
way to notify the build of this differing path, the only workaround
that I've found is to build a new version of boost (i.e. 1.53.0 from
source). So I'm curious how the PGDG toolchain handles this case.

Any help on these questions would be appreciated.

Thanks!
