I can't find one either. If the machine has perl/python, you could try
(use-modules (ice-9 rdelim) (ice-9 popen))
(read-line (open-pipe* OPEN_READ
"perl"
"-e"
"use Config; print $Config{path_sep}"))
or
(use-modules (ice-9 rdelim) (ice-9 popen))
(read-line (open-pipe* OPEN_READ
"python"
"-c"
"import os; print(os.pathsep)"))

I think the procedures described in (guile) POSIX are distributed in
different modules. E.g, `open-pipe' is located in `(ice-9 popen)', while
`chdir' is in the global namespace.
