This means that configure wasn't able to find working Lapack and FFTW libraries on your system. The Espresso distribution does contain a portable implementation of these libraries, so you can still compile and run it. However if you can obtain and use versions of these libraries optimized for your machine, you may experience significant performance improvements. If these libraries do exist on your system, but configure isn't able to detect them, you may give it some hints. The Espresso User's Guide (in the Doc directory of the Espresso distribution, or online at www.pwscf.org) tells you how. In fact, an fftw library has been found, but configure failed to locate the corresponding fftw.h file. This means that either your installation of FFTW is incomplete, or configure just looked in the wrong directories. Again, read the Espresso User's Guide for how to troubleshoot this. Gerardo
