The 'app' for Larry is GRASS-6.4.2.app, as packaged by William. My version is installed by a package installer called homebrew. Although not an application bundle, it also runs from a shell script rather than from a binary directly, i.e., :

> file /usr/local/bin/grass64                                                                                                            
/usr/local/bin/grass64: POSIX shell script text executable
> less /usr/local/bin/grass64

# PURPOSE:      The source file for this shell script is in
#               lib/init/grass.src and is the grass startup script. It
#               requires a source file because the definition of GISBASE
#               is not known until compile time and is substituted from the
#               Makefile. Any command line options are passed to Init.sh.

# Set the GISBASE variable

export GISBASE

Regarding the trunk fix, I now have a different compile error:
