Hmm, also, as shown in the first article, based on a discussion on this 
list awhile back, sometimes even when building in a prefix, GIMP looks 
in the wrong place unless you add a line about the GIO_EXTRA_MODULES, as 
per the following (your linux OS might need lib64 instead of lib);

PREFIX=$HOME/code/gimplch/install
export PATH=$PREFIX/bin:$PATH
export LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH
export XDG_DATA_DIRS=$PREFIX/share:$XDG_DATA_DIRS
export ACLOCAL_FLAGS="-I $PREFIX/share/aclocal"
export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH
export GIO_EXTRA_MODULES=/usr/lib/gio/modules
export SRC_DIR=$HOME/code/gimplch/build
