we use a nonstandard gcc, too here's how to do it. You need to create/edit 
user-config.jam. We decided to automatically create it. Here's the part where 
we configure the compiler:

cat >user-config.jam <<@@END@@
# Boost.Build Configuration
# Automatically generated by ${scriptname}

# Compiler configuration
using gcc : : ${GCC_BASEDIR}/g++-${GCCVERSION} : <compileflags>${flag} 
<compileflags>-I${buildprefix}/include <compi
leflags>-L${buildprefix}/lib <linkflags>${flag} 
<linkflags>-L${buildprefix}/lib ;
