ok, i'll try that...

this stuff about MPICH_LIBDIR2 was exactly the thing i needed to know...
i wasn't sure whether it isn't used for some other purposes, but if i
can redefine it i'll make use of it...

well, the build proceeded fine... i want this binary mainly for tests,
since not all nodes at clusters i use possess myrinet... sometimes i
experience that pmemd with mpich-p4 isn't putting the maximal load on
the processors - and i guess this could be related to slow ethernet
communication - myrinet should tell me, whether it is really so...
once more, thanks for your help. have a nice weekend,
