First of, I'd recommend leaving f9 alone (I'm going to deprecate all
linux base ports except fc4 and f10 soon).

I'm not sure if it's better but just an other idea:
-----
.if ${OSVERSION}<7000XX /*** XX should be find out ***/
IGNORE FreeBSD>=7.X is needed with Linux emulation 2.6.x.
.elif ${OSVERSION}<800076 && \
! defined (OVERRIDE_LINUX_NONBASE_PORTS) ||
! (${OVERRIDE_LINUX_NONBASE_PORTS} == f10)
IGNORE= you need to use non-default linux ports (define OVERRIDE_LINUX_BASE_PORT=f10 and OVERRIDE_LINUX_NONBASE_PORTS=f10)
.endif
-----
This check is not strict either. The thing is that both BASE and NONBASE
variables should be defined and have f10 value for OSVERSION<800076.
I have an item at my TODO list to switch to using USE_LINUX=f10[+] or
similar but it's not the highest priority and ENOTIME now...
