Indeed.  While I haven't looked very closely, I do think we have a
shot at faslink with the bfd relocation stuff.  faslink is what you
want for ease and simplicity; check out the info page.  Otherwise, you
need to rebuild your image from source, defining the EXTRAS make
variable with the libs you want.  This is described in the info page
also, as well as in an earlier post I submitted with the comments at
the head of littleXlisp.lsp, if I recall.  You can probably find the
discussion in the mailing archives.

I'll try to get a look at faslink sometime soon.  But right now, there
are more pressing things.  If you want a project, please dive in!

Take care,
