We're working with the latest StarPU release : 1.1.1.

Actually the only way to link StarPU with Magma is to define this kind 
of PKG_CONFIG_PATH. I don't know what should
be better, to let the configure detect Magma by itself of let the user 
decide to link with Magma or not with the --with-magma
option, like it's actually done for FxT for example.

Actually, it seems that the make step fails if we only give a 
PKG_CONFIG_PATH with this kind of error :

We tried to use the MAGMA_LIBS and MAGMA_CFLAGS environment variables 
proposed by the ./configure --help, and we
got another error :

We found that it could be a missing -DADD_ compiling option.
