+Some libraries want to know where other libraries are. For this to work,
+set the following environment variable
+
+ export PKG_CONFIG_PATH=${INSTALL_DIR}/lib/pkgconfig
+ export PATH=$INSTALL_DIR/bin:$PATH
+
+This relies on the presence of the F<pkgconfig> program. Below you find instructions
+on how to compile pkgconfig as well.
+
+Since we are compiling libraries dynamically, they must know
+where to find each other. This is done by setting an appropriate LDFLAGS.
+Unfortunately, the syntax again differs from system to system:

+If you have GNUmake installed and it is not called 'make',
+then do
+
+ export MAKE=gmake
+ export GNUMAKE=gmake
+
+otherwise just do
+
+ export MAKE=make
+
+=item Building pkgconfig
+
+As mentioned above, without pkgconfig the whole build process will be lots
+of pain and suffering, so make sure you have a copy on your system. If it is
+not available natively, here is how to compile it.
+
+ wget http://pkgconfig.freedesktop.org/releases/pkg-config-0.23.tar.gz
+ gunzip -c pkg-config-0.23.tar.gz | tar xf -
+ cd pkg-config-0.23
+ ./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC"
+ $MAKE
+ $MAKE install
