Hi Mason,

Instead of setting the BABL_LIBS/CFLAGS manually you should use 
pkg-config. To use pkg-config you set the 
PKG_CONFIG_PATH=/home/mason/localinstall/lib/pkgconfig

But there is an even better trick, the config.site. Put this content in 
the file /home/mason/localinstall/share/config.site:

export CFLAGS="-g -O0"
export PKG_CONFIG_PATH="/home/mason/li/lib/pkgconfig:$PKG_CONFIG_PATH"
export LD_LIBRARY_PATH="/home/mason/li/lib:$LD_LIBRARY_PATH"

and then that file will be sourced automatically whenever you invoke 
configure with that prefix. This means that the Makefile.am build 
dependencies that are setup are managed correctly and most of the time 
it is enough to make after a git pull --rebase.

HTH,
Martin
