Well, I meant `straightforward` more with respect to usage, not with respect to the actual magick involved. This approach allows me to run any fpc version by simply running fpc-<rev. number> on the command line. In that respect I think it is straightforward.

OTOH the involved switches seem to be a bit more exotic (as the 2.6.2 release does not even mention @, -Xp or -V in `fpc -help`) and this is indeed not so straightforward. Nonetheless, they are there and thus could be used.

As to answer another question you had: No, I don't use this approach because it's the only one I know, I use it because it suits my purposes best. I looked into several other ways of running multiple freepascal compilers on my machine (almost all of which have been stated by others) and this was simply the one that required the least effort and gave me exactly what I wanted.

This last one would introduce problems though, since all trunk version are currently version 2.7.1. Substituting <version> for a revision number would be possible, but it would make a terrible mess of your /etc directory IMHO.
