With help from some GIMP devs (Martin Nordholds and Mikael Magnusson), after
several weeks of trial and error, I've finally gotten the hang of building
GIMP 2.8 in Trisquel 5.0.
Install the build dependencies.
sudo apt-get install fontconfig gtk-doc-tools intltool libcairo2
libdbus-glib-1-2 libexif-dev libfontconfig1 libfreetype6 libgdk-pixbuf2.0-0
libgtk-3-0 libjasper-dev libjpeg62-dev liblcms1-dev liblcms-dev libmng-dev
libopenexr-dev libpango1.0-0 libpng-dev libpoppler-dev librsvg2-common
librsvg2-dev libtiff4-dev libtiff-tools libtool libwebkit-dev libwmf-dev
pkg-config python-dev python-gtk2-dev ruby libgirepository1.0-dev
gobject-introspection libpoppler-glib-dev libgfs-1-dev libcroco3-dev git
Set up the directory for GIMP to be installed in (in this example, I use
/opt/gimp).
sudo mkdir -p /opt/gimp/share/aclocal
Create the file /opt/gimp/share/config.site with the following contents (for
setting up build-environment variables).
export PATH="$PREFIX/bin:$PATH"
export PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH"
export LD_LIBRARY_PATH="$PREFIX/lib:$LD_LIBRARY_PATH"
export ACLOCAL_FLAGS="-I $PREFIX/share/aclocal $ACLOCAL_FLAGS"
export XDG_DATA_DIRS="$PREFIX/share:$XDG_DATA_DIRS"
Set up the build-environment variables.
export PREFIX=/opt/gimp
source /opt/gimp/share/config.site

Edit the file gimp-2.0.pc. With this edit, many plug-ins (like
Resynthesizer) did not work.
