is exactly the same as 5 so the two cannot coexist on the same

If someone would please confirm this, that would be great. If you
could tell me how to confirm it for myself so I don't have to
bother you next time, that would be even better. ;)
You can have both mysql5 and mysql5-devel installed at the same
time, but not active at the same time. The same goes for any other
foo/foo-devel port combination.
If you have mysql5 installed and would like to try mysql5-devel
instead, you would need to
sudo port deactivate mysql5
sudo port install mysql5-devel +server
In this particular case (mysql5 5.0.x and mysql5-devel 5.1.x) you
would also need to rebuild any programs (such as php5) that use the
mysql library, because the version number of the library has
changed. Otherwise you will find that php will complain about not
being able to find the (old) mysql5 library. To rebuild php5:
sudo port -nf upgrade php5
Some ports may not know about mysql5-devel and still try to depend
exclusively on mysql5. For example, if you've installed mysql5-devel
as above, and then try to install a port that requires mysql5,
you'll get an error as it tries to activate mysql5 but can't because
mysql5-devel is already active. Usually this is a bug, which should
be filed against that port so that the dependency can be rewritten
so that either mysql5 or mysql5-devel can be used.
Is this the case for rb-mysql?
I have both mysql5 and mysql5-devel installed as you stated above,
with mysql5-devel active and mysql5 deactivated. When I try and
install rb-mysql, it immediately fetches mysql5 and starts rebuilding
it (even though it's already installed, just inactive). Looking at the
Portfile (http://trac.macports.org/browser/trunk/dports/ruby/rb-mysql/Portfile
) the only relevant line I can see is the following:
depends_lib port:mysql5
So I guess there are three questions here: 1) Why would rb-mysql start
rebuilding mysql5 if it's already been installed? 2) Should a bug be
filed against rb-mysql to modify it so it can use mysql5-devel as
well? 3) What can I do in the mean time to get rb-mysql working with
mysql5-devel?
