saga @7.9.0_1: use a path-style dependency for unixODBC (if possible)

[cooljeanius (Eric Gallager)]

Currently saga has an unconditional dependency on unixODBC. Unfortunately, unixODBC conflicts with libiodbc, which I need to have installed for the KDE ports. If it's possible, it'd be nice for saga to use a path-style dependency so that it can use either unixODBC or libiodbc, in order to get around this conflict.

Other ports that can use either unixODBC or libiodbc offer variants for that choice. I assume a path-style dependency was not used because they are not drop-in replacements for one another.

[cooljeanius (Eric Gallager)]

yeah doing it as variants could be another solution

Vincent made your proposed change in [eb9357a25f17f52dd40c4c7a2684493eb3b4848b/macports-ports] but I still don't think it's appropriate. They don't provide the same files, so they're not drop-in replacements for one another. Use variants instead.

libiodbc provides:

• /opt/local/lib/libiodbcinst.dylib
• /opt/local/lib/libiodbc.dylib
• /opt/local/lib/libiodbc.2.dylib
• /opt/local/lib/libiodbcinst.2.dylib

unixODBC provides:

• /opt/local/lib/libodbcinst.2.dylib
• /opt/local/lib/libodbccr.dylib
• /opt/local/lib/libodbcinst.dylib
• /opt/local/lib/libodbc.2.dylib
• /opt/local/lib/libodbccr.2.dylib
• /opt/local/lib/libodbc.dylib

Fair enough, I hadn't checked this, and using a path dependecy seemed an elegant workaround. I’ll modify the Portfile to make use of variants.
