try '--with-fastblas'

see if blas was detected:

# fgrep blas config.cache 
ac_cv_lib_cblas_cblas_dgemm=${ac_cv_lib_cblas_cblas_dgemm='yes'}
ac_cv_lib_f77blas_dgemm_=${ac_cv_lib_f77blas_dgemm_='yes'}

Also, 'rm config.cache' or 'make distclean' before running 'configure'
again.

after 'autogen' you don't need to run 'configure'.

the last cvs does not need anything special. But check 'config.log'

configure:2735: checking g77/f2c compatibility
configure:3153: checking for ATL_xerbla in -latlas
configure:3195: checking for cblas_dgemm in -lcblas
configure:3235: checking for dgemm_ in -lf77blas   
configure:3678: checking for cheev_ in -llapack    
configure:3716: checking for cheev_

if you see same error around here, atlas (or other blas) was not
detected.
