Sorry to be the bearer of bad news...
I configured on an SGI Altix UV with only "--enable-debug --enable-static
--prefix=..."
The configure script found the sn/xpmem.h header and threfore enabled
btl:vader:
--- MCA component btl:vader (m4 configuration macro)
checking for MCA component btl:vader compile mode... static
checking --with-xpmem value... simple ok (unspecified)
checking --with-xpmem-libdir value... simple ok (unspecified)
checking xpmem.h usability... no
checking xpmem.h presence... no
checking for xpmem.h... no
checking sn/xpmem.h usability... yes
checking sn/xpmem.h presence... yes
checking for sn/xpmem.h... yes
looking for library without search path
checking for xpmem_make in -lxpmem... yes
checking if MCA component btl:vader can compile... yes
However, not only was btl:vader failing at runtime on the Altix when I last
checked, but the version of the code in 1.7.5rc5 won't build:
Making all in mca/btl/vader

error: xpmem.h: No such file or directory
I think the safest/fastest fix is the following 1-line change to prevent
locating sn/xpmem.h, which is Altix-specific:

This patch is intended for 1.7 only - lets leave the trunk as-is.
