Curtis,

If you don't have the mythtv-v0.2.....tar.bz2 file something has gone 
wrong with the build.

Suggest you try

./mythbuild.sh -2 -Q 5.4.0 -l -v

the -l creates a mythbuild.log file
the -v gives more information during the build - effectively debug.

At the end of the mythbuild.log file (and on-screen) you should get something like
