+If you are using gfortran, you will have to locally install a version >= 4.5 as current linux distributions don't yet ship 4.5. This is not very hard to do and ''causes absolutely no harm''.  However, you have to make sure that the environment is configured correctly when building and running WHIZARD:
 {{{
-   PATH=<path to the gfortran-4.5 binary>:$PATH
-   LD_LIBRARY_PATH=<path to the gfortran-4.5-libraries>
+   export PATH=<path to the gfortran-4.5 binary>:$PATH
+   export LD_LIBRARY_PATH=<path to the gfortran-4.5-libraries>:$LD_LIBRARY_PATH
 }}}
-are set correctly.  You will get strange runtime errors, if the new compiler links WHIZARD to the old compiler's runtime libraries.
+While the soname of the gfortran runtime has not changed, some of the internal changes are crucial for the operation of WHIZARD, and you will get weird runtime errors if WHIZARD links to old compiler's runtime libraries.
