something like that
dl_libs=
have_dl="no"
AC_CHECK_LIB([dl], [dlopen],
[AC_CHECK_HEADER([dlfcn.h],
[
dl_libs="-ldl"
have_dl="yes"
])])
if test "x${have_dl}" = "xno" ; then
AC_MSG_ERROR([Usable libdl not found! Apollo port not yet complete.])
fi
AC_SUBST(dl_libs)
(not tested) and add @dl_libs@ to *_LIBADD
