As the other poster noted, you're missing a library. In this case, it's 
going to be a file called libgfortranbegin. On my FC5 system I found 
that file by running the command "locate libgfortranbegin". The result was:
/usr/lib/gcc/i386-redhat-linux/4.1.0/libgfortranbegin.a

To find out what package you need to install to get this, I ran "rpm -qf 
/usr/lib/gcc/i386-redhat-linux/4.1.0/libgfortranbegin.a", and the result is:
gcc-gfortran-4.1.0-3

So, what this means is that in order to run mkoctfile, you need to have 
the fortran compiler installed. You can install this by running "yum 
install gcc-gfortran" as root, and it will download and install it for 
you. This error is partly my fault since I'm the packager of the Fedora 
Octave packages. I'll fix this in future releases by making the 
octave-devel package (which is the package that mkoctfile belongs to) 
requires gcc-gfortran.
