DTrace Broken?

Hey fellow current users,

Looks like dtrace is broken in current:

# dtrace -l -f acl
dtrace: invalid probe specifier acl: "/usr/lib/dtrace/psinfo.d", line 37:
syntax error near "uid_t"

Line 37 shows:
       uid_t   pr_uid;         /* real user id */

Looks good to me, but why is dtrace complaining?

Thanks,

Shawn Webb
