Portfiles are Tcl, which is a full programming language, so when the question is "Does MacPorts have the ability to …" the answer is usually yes, depending on how much code you want to write.

In MacPorts these days, "pre-10.5" means Mac OS X 10.4 a.k.a. darwin 8. MacPorts doesn't run on earlier systems anymore. So you can put the required code for this scenario inside a platform darwin 8 block:

platform darwin 8 {

Instead of an entire older version of the source file, usually I'd suggest making a patchfile (which reverts whatever the bad parts are of the new file), and then you can apply that patchfile conditionally on darwin 8.
