Hi,
please consider this patch:
http://bknr.net/trac/changeset/2795?format=diff&new=2795
It fixes loading of system calls for Linux and FreeBSD. I have opened a bug with Clozure to make them move to a unified system call loading interface so that applications do not need to dispatch on an architecture symbol, but until that went into CCL, the fix should be fine.
Thanks, Hans
