Filter a library from the list of libraries?

(Many thanks to Steven on answering my last question so quickly)
..
My next challenge is to remove the -ldl library from the list of libraries handed to the shared library linker a.k.a the link.dll action.
I'm trying to use MATCH for this with no success.


    local libraries = [ feature.get-values     <libraries>  : $(options) ] ;
    toolset.flags clang-vxworks.link     LIBRARIES    : $(libraries) ;

    # link shared libraries without libld.a
    for local e in $(libraries)
    {
        local dll_libs = [ MATCH "-l(?!dl)\w+" : $(e) ] ;
    }
    toolset.flags clang-vxworks.link.dll DLL_LIBS : $(dll_libs) ;


Could someone identify my issue? (perhaps something in the regex needs escaping?) or perhaps suggest a better method to accomplish the same thing?

Thanks,
