Subject: libopenmpi-devel problems

I am experiencing two problems with libopenmpi-devel-1.7.2-1:

1. The package contains an implementation of libevent2 that clashes with 
files in libevent-devel-2.0.21-1. For instance, both packages contain 
/usr/include/event2/event.h [1]. Linux distros tend to get round this 
clash by placing the openmpi include files in their own directory (e.g. 
Fedora uses /usr/include/openmpi-i386/event2/event.h [2]; Debian has 
/usr/lib/openmpi/include/openmpi/opal/event/event.h [3]).

2. The version of event.h in libopenmpi-devel includes "opal_rename.h", 
which is not provided in libopenmpi-devel (or any other Cygwin package 
for that matter). Hence, a programme that includes event.h will fail to 
compile.

Marco: If you agree with my analysis above, please could you repackage 
libopenmpi-devel to fix these issues.

Many thanks in advance,

Dave.
