[mpich-discuss] Using RPATH

[Dave Goodell]

Looks like I botched this when fixing ticket #1497:

http://trac.mcs.anl.gov/projects/mpich2/ticket/1479

I forgot we were still using the result of "--enable-rpath" in the compiler wrappers even though we stopped having control of this for binaries/libraries built by the MPICH2 build system.  So our "@enable_rpath@" substitutions in the wrappers no longer get substituted and the `test "X$enable_rpath" = "Xyes"' always evaluates to false.

I'll straighten this out today.

It appears that that behavior changed in the past week or two because I rebuilt mpich2 trunk and the option has vanished from the wrappers. I just want to know whether it's intentional (in which case I will make a permanent workaround on my end) or not.
