Hi Eneko, and thanks! for responding.

I build GIMP from git in a prefix to avoid interfering with GIMP 2.8 installed from Gentoo portage, and so I'm not sure that modifying /etc/ld.so.conf is the right thing to do.

I have three different installations of GIMP in three different prefixes. So I want libmypaint in prefix1 to link with GEGL in prefix1, and GIMP in prefix1 to look for libmypaint-gegl also and only in prefix1, and so forth for the other two prefixes.

Here's how I set up the first prefix:

export PATH=$PREFIX/bin:$PATH
export ACLOCAL_FLAGS="-I $PREFIX/share/aclocal"
export GIO_EXTRA_MODULES=/usr/lib/gio/modules
export SRC_DIR=$HOME/data/gimp/gimpdefault/build

Here's the command to build libmypaint:

scons prefix=$HOME/data/gimp/gimpdefault/install use_sharedlib=yes enable_gegl=true

libmypaint-gegl.so is located in /home/elle/data/gimp/gimpdefault/install/lib/, along with libmypaint.so and the two corresponding ".a" files.

But GIMP still isn't finding libmypaint-gegl.so.
