This is a known issue [1].  The bigloo REPL is linked against the
mono-threaded GC.  The consequence is that symbols needed by the
pthread library are not defined in the GC library.

You can write and build your own pthread-enabled REPL using the simple
following code, quoting from [1]:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----
$ cat > bglrepl.scm << EOF
(module bglrepl
(library pthread))

(repl)
EOF
$ bigloo bglrepl.scm -o bglrepl
$ ./bglrepl
:=> (load "test-pthread.scm")
^D

Hope this helps
