This means that the linker cannot find libgfortran.so.3 at run-time.
This usually happens when you are using compilers that are _not_ found
in /usr/bin and the directories with the libraries are not located by
your linker (ld).
The typical solution is to find where these libraries are located and
add them to LD_LIBRARY_PATH. In bash, this would be something like:
swails.Batman ~ $ locate libgfortran.so.3
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3/libgfortran.so.3
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3/libgfortran.so.3.0.0
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3/32/libgfortran.so.3
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3/32/libgfortran.so.3.0.0
swails.Batman ~ $ export
LD_LIBRARY_PATH=/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.3:
$LD_LIBRARY_PATH
You will want to put the latter command into your .bashrc file so it
appears every time you log in. [1]

[1] An alternative is to modify the configuration file for the ld loader
(on my machine it is /etc/ld.so.conf via configurable files
in /etc/ld.so.conf.d/). Using LD_LIBRARY_PATH is easier and safer if
you're not sure what you're doing.
