Hello
I'm using a Chez scheme installed by guix package manager. The problem
is *this* chez scheme can not load system shared library correctly:
#+begin_example
> (load-shared-object "libssl.so")
Exception: (while loading libssl.so) libssl.so: cannot open shared
object file: No such file or directory
Type (debug) to enter the debugger.
#+end_example
The `libssl.so' is in the standard `/usr/lib/' directory, the expression
above *should* load the library without problem. Now if I provide a full
path,
there is another error:
#+begin_example
> (load-shared-object "/usr/lib/libssl.so")
Exception: (while loading /usr/lib/libssl.so) libcrypto.so.3: cannot
open shared object file: No such file or directory
Type (debug) to enter the debugger.
#+end_example
This time, it complains `libcrypto.so.3' is missing, which essentially
is the same problem as above, that is, the scheme system can't find system
shared library from standard paths (libssl.so depends on libcrypto.so).
A full session is provided below:

#+end_example
It seems the Chez scheme, which installed by guix, does not not follow
the searching mechanism described in "man 8 ld.so". On the
other hand, if I build a Chez scheme from source code, without any
dependency of guix, then there is not any problem of loading system
libraries.
Since guix is essential to me, please give advice on how to resolve the
problem.
