Thanks for the response, Paul. Yes, I had remembered to do 'make install'.
I did find a workable solution, though, so I wanted to post it for the sake of future users who may have similar problems. Basically, I just went into the 'lwpostgis.sql' file and commented out the lines that called the 'topologypreservesimplify' function and everything then compiled nicely. Hopefully that function isn't integral to PostGIS functionality! The comments at that line specify that GEOS > 3.0.0 is needed for this function, but I have 3.0.3, so I'm still unsure why the error was occurring in the first place.
Anyways, all is well for now.

Did you remember to 'make install'? The SQL file is referencing a C
function that doesn't exist in your postgis .so file. So somewhere you
have a mis-match between versions. Ensuring that all old things are
*removed* and all new things *installed* might do the trick.
