yes.

But then, I'd have to make sure that the gdm startup and backend startup 
stuff was using the same PATH, for me it was easier to build 0.18.1 and 
latest SVN and then, using the symlinks, I was guaranteed that I was using 
the latest libs. I also had all sorts of problems when the shared loader 
could see both libraries. Now, I just run a script "mythswitch SVN|STABLE" 
and all gets reset.

Build 0.18 from source and install in /usr/local/mythX - once you have 
everything working, remove the relevant files from /usr/bin, /usr/lib, etc. 
- ie, do a manual unistall.  You will find these files in 
/usr/local/mythX/bin, lib. You can rely on PATH precedence for the binaries 
but not for the shared libs.
