@@ -124,6 +124,39 @@ The ``buildable`` does not need to be paired with external packages.
It could also be used alone to forbid packages that may be
buggy or otherwise undesirable.
+Virtual packages in Spack can also be specified as not buildable, and
+external implementations can be provided. In the example above,
+OpenMPI is configured as not buildable, but Spack will often prefer
+other MPI implementations over the externally available OpenMPI. Spack
+can be configured with every MPI provider not buildable individually,
+but more conveniently:
+
+.. code-block:: yaml
+
+ packages:
+ mpi:
+ buildable: False
+ openmpi:
+ paths:
+ openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64: /opt/openmpi-1.4.3
+ openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug: /opt/openmpi-1.4.3-debug
+ openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64: /opt/openmpi-1.6.5-intel
+
+Implementations can also be listed immediately under the virtual they provide:
+
+.. code-block:: yaml
+
+ packages:
+ mpi:
+ buildable: False
+ openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64: /opt/openmpi-1.4.3
+ openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug: /opt/openmpi-1.4.3-debug
+ openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64: /opt/openmpi-1.6.5-intel
+ mpich@3.3 %clang@9.0.0 arch=linux-debian7-x86_64: /opt/mpich-3.3-intel
+
+Spack can then use any of the listed external implementations of MPI
+to satisfy a dependency, and will choose depending on the compiler and
+architecture.
