+Here's a list of not so common problems that you might encounter when building WHIZARD that didn't make it into the [source:/trunk/INSTALL INSTALL file].
+
+=== Compiler and Shared Library search PATHs ===
+
+If you are using gfortran, you will have installed a version >= 4.5, which is not yet the one that came with your Linux distribution.  This is not very hard to do and ''causes absolutely no harm''.  Nevertheless please make sure that the environment variables
+{{{
+   PATH=<path to the gfortran-4.5 binary>:$PATH
+   LD_LIBRARY_PATH=<path to the gfortran-4.5-libraries>
+}}}
+are set correctly.  You will get strange runtime errors, if the new compiler links WHIZARD to the old compiler's runtime libraries.
 
 === Parallel Make and Slow Filesystems ===
