There is an old bug report #21076 on dynamic-link:

Say you have a file, dynamic-link can't load it

     (dynamic-link "") => exception

even if there is a file

   $ cat /usr/lib64/

it fails with (dynamic-link "libyaml")

I have submitted the following patch, which at least
makes the first version work.  If you think this is a libtool
but you may be right, but the bug report on this has not
been touched for 8 years:

This patch fixes issue with libtool and OSes which use
non-standard extensions for shared libraries.  The libltdl
function lt_dlopenext expects the argument to have a standard
extension or no extention.  Arguments reflecting shared object
files with non-standard extensions will fail to load.  For
example, my system has /usr/lib64/  w/o this
patch (dynamic-link "") does not work; with it,
it does.  Go figure.
