Compiling EMAN on Ubuntu 10.04 x86_64 platform needs pay attentation to the fftw libraries.
By default the EMAN compilation will link to libfftw.so and librfftw.so, which compiles but will seg fault at runtime when call fftw routine.
You need link to single precision fftw libraries libsfftw.so.2 and libsrfftw.so.2.
