The build runs fine. Thanks! Now GRINS can also be built on that.
Thanks for the update!
BTW, there're always warning like

Probably you can give an answer.
The answer is simple but unsatisfying: the openmpi headers on Ubuntu
14.10 aren't strictly C++11 compatible, by default libMesh tells your
compiler to run in C++11 mode, and the only reason it compiles at all
is that gcc is nice enough to treat the incompatibility as a warning
rather than an error for now.
IIRC I wasn't able to get gcc to ignore those warnings via our
ignore_headers.h pragmas. You might be able to manually set
-Wnoliteral-suffix in your CXXFLAGS?
