Hmm, haven't seen anything like this, and have done a number of 
incremental rebuilds since checking it in (this is on FreeBSD).

Can you provide more details about the error, and are you using a 
different SCons version?
I'm using SCons 1.2.0.d20090223 here.

mkdir_func() in SCons/Defaults.py looks as though it should ignore 
EEXISTS correctly already, so I wonder why this would cause a problem.

Having said that, SCons' support for symlinks is very poor.

I fought with SCons for a while before I could get it to work, and 
what's in tree is not 100% 'the SCons way' as the .so symlinks are not 
in the dependency graph; they're just actions.

cheers,
BMS
