ZendOptimizer and libm.so.2?

[Mark]

Hello,

Is there a particular reason ZendOptimizer
(/usr/ports/devel/ZendOptimizer) for PHP 4.4.4 requires FreeBSD 5.x or
higher? Near as I can tell, only reason it wouldn't run really, is because
of the absence of libm.so.3. But I resolved to be bold, and made a symlink
for libm.so.3 to libm.so.2, and now my new ZendOptimizer works just
flawlessly.

I hope someone can shed some light on this.

Thanks,

- Mark
