I have tried to install development version of octave-4.1.0+ from the tarball
but the make failed giving the following message:

CXX      liboctave/util/liboctave_util_libutil_la-sparse-util.lo

Configure displayed some warnings:

configure: WARNING: CAMD library not found.  This will result in some lack of
functionality for sparse matrices.
configure: WARNING: COLAMD library not found.  This will result in some lack
of functionality for sparse matrices.
configure: WARNING: CCOLAMD library not found.  This will result in some lack
of functionality for sparse matrices.

Since I don't know whether they may have any relation with the error, I tried
configure using options:

--with-amd-includedir=/usr/include/suisparse 
--with-amd-libdir=/usr/lib64  
etc.

and using the respective   --without-... options.

Nothing changed in either case. The error abode.

I had been able to install octave-4.0.1 in the same platform (same compilers,
same autotools version, etc) without problems.
