 Hi

 I am trying to install two versions of openmpi. I already have @3.0.0
 installed, but it seems to be somewhat incompatible to hdf5. For debugging
 reasons, I tried to install openmpi 1.10 using the following command:

 sudo port install openmpi-gcc7 @1.10 +threads

 It shows no error and installs properly, but it installs the wrong
 version, 3.0.0, which is already installed. In fact it does not build
 anything: it only scans for errors and proceeds.

 I expect that -gcc7 and +threads are not relevant to this ticket.

 Thanks
