php5-dba: add a new variant for db4 support

[tinhkyaw@…]

I added a new variant to my local php5 Portfile for db4 support so that I could use db4 via dba extension in php. I would like to contribute my changes back to macports. Can someone please review my changes and let me know if you find any issues?

Thanks very much,

Tin

This will be solved by the new php5-dba port; see #20056.

php5-dba was created in r58585, but I was thus far unable to figure out how to inform it where MacPorts installs db4 (I keep getting "checking for db4 major version... configure: error: Header contains different version"), so that variant is still missing for now.

Hi Ryan,

Thanks for looking into the issue.

Now I remember running into similar issues before. I think php5 compilation script ignores the prefix argument passed in --with-db4= and just looks for everything under /usr/local. Hence, my hacky solution was to make the following 2 symlinks in order for things to work:

1. ln -s /opt/local/include/db46 /usr/local/include/db4.6

2. ln -s /opt/local/lib/db46/* /usr/local/lib/

I think the right thing to do is probably to track down fix the issue in the src for php5..
