I have encountered this issue with dynamic-link.
I propose a small patch to Guile (works on v3.0.1) to address it.
At least this allows me to load the file if I know the exact name.
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/libyaml-0.so.2. w/o this
patch (dynamic-link "libyaml-0.so.2") does not work; with it,
it does. Go figure.
