Arrange for your aclocal.m4 to include ltdl.m4, and then in configure.ac:
~ AC_LTDL_DLLIB
~ AC_SUBST([LIBADD_DL]) # probably not necessary for libtool >= 1.5
and in Makefile.am:
~ program_LDADD = @LIBADD_DL@
Beware the "Great Renaming" wherein, hopefully, libtool 1.6 will move all
macros into the LT_* and LTDL_* namespaces. autoupdate is your friend.
Cheers,
Gary.
