Problem solved, it compiles now.
It turned out I forgot to unload the module for an outdated boost
version already installed on the cluster.

INCLUDE_DIR was empty. However:

[kastaun at i909 ~]$ env | grep -i boost     
LD_LIBRARY_PATH=/opt/boost/1.33/lib64:/opt/openmpi/1.4.2/intel-10.1/lib:/opt/ofed/1.3.1-lustre1.6.5.1/lib64:/opt/libnuma/2.0.2/intel/lib64:/opt/gsl/1.12/intel/lib:/opt/hdf5/1.8.5p1/gnu/lib:/opt/intel/cce/10.1.018/lib:/opt/intel/fce/10.1.018/lib

In the directory $CPATH I found a boost version of regex.h,
which had a line 
#include <boost/cregex.hpp>

This picked up the boost version I added via the cactus include path,
which explains the mixed dependencies below.

[kastaun at i909 Cactus]$ grep regex main/Parameters.c.d 
 /opt/boost/1.33/include/regex.h \
 /u/ap/kastaun/sim_build/boost_1_46_1/boost/cregex.hpp \
 /u/ap/kastaun/sim_build/boost_1_46_1/boost/regex/config.hpp \
 /u/ap/kastaun/sim_build/boost_1_46_1/boost/regex/v4/cregex.hpp \
 /u/ap/kastaun/sim_build/boost_1_46_1/boost/regex/v4/match_flags.hpp \
 /u/ap/kastaun/sim_build/boost_1_46_1/boost/regex/v4/error_type.hpp \

 

Anyway, after unloading the boost module, deleting the whole
configuration, and starting from scratch, it compiled fine.
My thorns used the boost version I specified via CPPFLAGS, without
affecting the rest of Cactus.
