Hi Michael,
Sorry for the late reply. I have now tried GluCat 0.1.9 (as yet unreleased) 
with gcc 3.3.4, 4.0.1, 4.0.2 (snapshot), 4.1.0 (snapshot) and Boost 1.31.0, 
1.32.0, 1.33.0. Results are summarised below.
Summary of the summary is that Boost 1.33.0 works. Thanks.
Best regards

Summary of GluCat compilation and test results

g++   Boost  result
3.3.4 1.31.0 OK
4.0.1 1.31.0 compilation error
4.0.2 1.31.0 compilation error
4.1.0 1.31.0 compilation error

The compilation errors with Boost 1.31.0 and g++ 4.X.Y are of the type:
../boost/numeric/ublas/matrix_sparse.hpp:3880: error: dependent-name 
‘boost::numeric::ublas::compressed_matrix<T,F,IB,IA,TA>::value_type’ is 
parsed as a non-type, but instantiation yields a type
../boost/numeric/ublas/matrix_sparse.hpp:3880: note: say ‘typename 
boost::numeric::ublas::compressed_matrix<T,F,IB,IA,TA>::value_type‘ if a type 
is meant

The compilation warnings with Boost 1.33.0 and g++ 4.X.Y are of the type:
