There could be a number of problems:

Where the libs compiled with STLport (even a small error in the STLport
include path could have messed this up)?
The debug STLport libs are probably compiled by jam with __STL_DEBUG
defined, your source will need to set this also.

If you want to check your jam compiled libs, get a dump of the symbols they
contain - if they're using the Dinkumware std lib then you'll see them
referencing std::basic_string, release STLport will reference
_STL::basic_string, and debug STLport will reference _STLD::basic_string.

Failing that just create a static lib project in your IDE and add the regex
sources to that with the build setting you want (this is probably the
quickest solution IMO).

Finally define BOOST_REGEX_STATIC_LINK to suppress the import/export
warnings
