[Wien] lapw1para error while running k-point parallel calculation

It seems that you do not have a proper environment when doing the   ssh hostname ....

a) Are you sure the names "localhost" work properly ? Usually you should put there the correct hostname so that you can do
    ssh hostname echo $WIENROOT
b) do you get the proper directory from the above command ? Your basic error seems to be:
    12778bash: lapw1c: command not found

c) can you do:
    ssh hostname
    cd case_dir     (where your files are)
    x lapw1

d) the parallel lapw1 works like the above, but does it at once:
    ssh hostname;cd $PWD;lapw1 lapw1.def

I tried it first with test-case from the benchmarking Wien2k web page. I wanted to do a benchmarking such as the one in the thread starting from:
