Hi Alan,

FreeBSD jails don't affect the output of kernel-related commands,
including the output of uname (if will show you the truth, i.e. the
configuration of the physical machine).

Try to set

MACHINE_ARCH
OSVERSION
BRANCH "STABLE"
REVISION "7.2"
UNAME_p
UNAME_m
UNAME_s
UNAME_r
UNAME_v

according to the jailed system and test the output of `uname -a`. If you
set them properly, it is virtually impossible for the compiler to find
out that it's operating in a jail (except if it uses sysctl, which is
not the case with the software included in TL).

HTH,
