[mvapich-discuss] MVAPICH2 1.5 hwloc issue

[Jonathan Perkins]

Thanks the for the note.  We've recently resolved an issue where our
internal version of hwloc was not being properly built in our shared
library.  Can you describe your issue a bit more.  Are you seeing
build or linking failures or unexpected operation at run time?
