+
+    <para><application>PDL</application> is a collection of over 90
+    <application>Perl</application> modules. Some of these modules require
+    additional libraries, packages and/or <application>Perl</application>
+    modules for full functionality. Listed below are the modules which require
+    additional software or configuration. If you don't need a particular
+    module's functionality, you don't need to install its dependencies. The
+    dependency tree for each module is listed downward, meaning you'll need to
+    start at the bottom of a module's tree and work up. The dependencies are
+    listed in the same order as they are in the
+    <filename>DEPENDENCIES</filename> file, found in the package source
+    tree.</para>
+
+    <para>This package (and many of the dependency packages) requires a Fortran
+    compiler for full functionality of all the different modules. The
+    <command>gfortran</command> compiler installed with the current BLFS
+    version of <application>GCC</application> (&gcc-version;) will not work. If
+    you want to compile the parts of this package that require a Fortran
+    compiler, you'll need to install a
+    <application>GCC</application>-3.x.x version of Fortran. The
+    <application>GCC</application> developers recommend using Fortran from
+    <application>GCC</application>-3.4.6. You can find specific instructions
+    to install a <application>GCC</application>-3.4.6 compiler on the
+    <ulink url="&blfs-wiki;/gcc3">BLFS
+    Wiki</ulink>. <!-- Alternatively, if you have a need to install
+    <xref linkend="gcc3"/>, you can add the Fortran compiler to the list of
+    compilers installed in those instructions. Don't forget to put the
+    directory containing the <command>{g,f}77</command> commands at the
+    beginning of your <envar>PATH</envar> environment variable before
+    beginning the compilation.--> </para>
