You can specify the directory for the extra libraries to the configure
script (or extconf.rb too).  E.g.

  ./configure --with-xxx-yyy=DIR

where xxx is either

  opt		extra software path in general
  dbm           path for dbm library
  gdbm          path for gdbm library
  x11           ...for X11..
  tk            ...for Tk...
  tcl           ...for Tcl...

and yyy is either

  dir      	specifies -I DIR/include -L DIR/lib
  include       specifies -I DIR
  lib           specifies -L DIR

Hope this helps.

I should have document these somewhere.  I'll CC this mail to the
ruby-talk list for the record.
