[aur-general] Problem with root permission

[Michele Mocciola]

I'm having trouble building PKGBUILD for mpi version of code-aster:
during compilation process install script must run mpixec; because of fakeroot, mpiexec believes that is being runt by root and so looks for file /etc/mpd.conf, for its owner, that must be root, and for its permissions that must be 600; problem start when install script tries to open mpd.conf, because of permissions 600 it can't open it and so it closes with error.
The only solution I found is to run makepkg as root (e.g. sudo makepkg --asroot). 
Do you think there are other solution for this problem?
MPI implementation I use is mpich2.
Thanks in advance.
