Actually, this is GCC dependent I'm afraid, as __FreeBSD__ is in the default 
defines of the compiler. Most likely the GCC 3.4 shipped with base system and 
the ones shipped with ports use different ways to define __FreeBSD__. Using 
it to desume the version is not correct anyway, instead one should use the 
__FreeBSD_version macro from <osreldate.h>:

#define __FreeBSD_version 602100

this is from a 6.2-BETA2 insteall.

/usr/local/* is used only from ports, that is not the only way to install 
software on a FreeBSD system, most likely it should be local because it might 
be disruptive to force looking there on systems where /usr is used instead.

Can you post the error? Because it seems pretty strange that this way it 
failed, as -lavutil should have been more than one time in the linking line.

I should probably check again the current SVN now that Luca committed 
the --as-needed thing and it should be fixed (especially considering I have 
to fix his snapshot in portage too :P).
