Yes, this happened to me as I switched from glibc1 to glibc2 on Linux.
It is a simple configure.in problem, I was too specific in writing it.
Here is the end of configure.in in guile-hobbit-1.3.3b which solves
this problem::

case $host_vendor in
    hp)
        UNEXEC=unexhp9k800
        TFLAGS="-Wl,-a -Wl,archive_shared -ldld"
        ;;
    sun)
        UNEXEC=unexelf
        TFLAGS=
        ;;
    *)
        case $host_os in
            linux-gnu*)
                UNEXEC=unexelf
                TFLAGS="-Wl,-u -Wl,free"
                ;;
            *)
                echo "Unexec pas defini"
                exit 1
                ;;
        esac
        ;;
esac
AC_SUBST(UNEXEC)
AC_SUBST(TFLAGS)
