Try building igraph as follows:

./configure --with-external-blas --with-external-lapack --with-external-arpack

(you'll have to install the BLAS, LAPACK and ARPACK packages from Ubuntu of 
course).
This should do the trick until we sort out the problems with f2c (probably with 
tomorrow's nightly build).

Have you used the Intel C Compiler recently to compile igraph by any chance? 
The igraph library does not refer to these symbols when I compile it on Ubuntu 
using gcc.
