Bug#766134: coinutils: lapack and blas support is not really enabled

[YunQiang Su]

Package: src:coinutils
Version: 2.9.15-1
Severity: serious
Tag: patched

liblapack and libblas are in the building depends list while in build log,
there are lines:

checking whether -lblas has BLAS... no
checking for COIN-OR package Blas... skipped check via pkg-config,
redirect to fallback
checking for COIN-OR package Blas (fallback)... no, dependency
coinblas not available
checking whether -llapack has LAPACK... no
checking for COIN-OR package Lapack... skipped check via pkg-config,
redirect to fallback
checking for COIN-OR package Lapack (fallback)... no, dependency
coinlapack not available

If add gfortran to build-deps, it works well like this[1]

checking whether -lblas has BLAS... yes: -lblas
checking whether LAPACK is already available with BLAS library... no
checking whether -llapack has LAPACK... yes: -llapack


When blas and lapack enabled, coinor-libcoinutils-dev should depends on
liblapack-dev and libblas-dev. if not so, coinor-osi will ftbfs, as
the pkgconfig file
contains such informations.
