failed to build gcc :(

   gcc: WARN
   gcc: WARN The following runtime dependencies have more than one version
   gcc: WARN release in the full dependency chain:

   gcc: WARN   * core/gmp ( core/gmp/6.1.2/20170526062114 core/gmp/6.1.0/20170513202112 )
   gcc: WARN
   gcc: WARN The current situation usually arises when a Plan has a direct
   gcc: WARN dependency on one version of a package (`acme/A/7.0/20160101200001`)
   gcc: WARN and has a direct dependency on another package which itself depends
   gcc: WARN on another version of the same package (`acme/A/2.0/20151201060001`).
   gcc: WARN If this package (`acme/A`) contains shared libraries which are
   gcc: WARN loaded at runtime by the current Plan, then both versions of
   gcc: WARN `acme/A` could be loaded into the same process in a potentially
   gcc: WARN surprising order. Worse, if both versions of `acme/A` are
   gcc: WARN ABI-incompatible, runtime segmentation faults are more than likely.
   gcc: WARN
   gcc: WARN In order to preserve reliability at runtime the duplicate dependency
   gcc: WARN entries will need to be resolved before this Plan can be built.
   gcc: WARN Below is an expanded graph of all `$pkg_deps` and their dependencies
   gcc: WARN with the problematic lines noted.
