php5-mysql +mysql5 error

[Scott Webster]

It's not really that you can't put stuff in /usr/local... it's just
that if you do, likely macports won't work properly, and we won't be
able to support it, so you're on your own.  It will depend on the
ports you use etc etc.  There are large numbers of problems reported
on the mailing list and in the ticket system that in the end are
caused by other software the user has installed in /usr/local.

But if it's /usr/local we're talking about (/usr/local/lib, /usr/local/include), then it's a problem because the compiler looks there without you needing to tell it to. We'd love to tell the compiler not to do that, but we don't know how to do so in a way that doesn't have other consequences. It's come up many times before and the best we can offer at this time is don't install software in prefix /usr/local.
