--- Comment #1 from Pierre-YvesChibon <pingou@xxxxxxxxxxxx> ---
* Spec is clean
* License is GPLv2+
! In the sources, three files (src/expm.c, src/logm-eigen.c and
src/expm-eigen.c) have the following header:

 *  The functions therein use LAPACK and BLAS routines. Nicely
 *  formatted man pages for these can be found at
 *
 *    <http://www.mathkeisan.com/UsersGuide/E/>
 *
 *  AUTHORS: Christophe Dutang, based on code eigen,
 *
 *  i.e., function 'modLa_rg' and 'modLa_dgesv' in R's
 *  <Rsource>/src/modules/lapack/lapack.c, used in eigen()

Could these be bundled? I did not check if they have been changed or not

* Builds errors on F20:

So we have to see about the headers and whether you want the F20 branch or not
:)
