[Wien] error in mixer

Dear w2kusers,

 I compiled successfully the latest version of wien2k code on IBM power5.

I tested the code  4 carbon atom/unit cell (in bulk graphite structure), 
spin-unpolarized, spin-unpolarized+spin-orbit. It works.

However, when I (just for testing) use "runsp_lapw' it gives error in 
mixer.
(To do the spin-polarized calculation, I did the initilization again in a 
new 
directory to avoid the mix-up but this time with dstart -up and dstart-dn. 
The outputs 
of the initialization are generated properly)


 'MIXER' - can't open unit:  7
 'MIXER' -        filename: C_HEX.inc

I checked file C_HEX.inc  exists in the working directory and it is not 
empty.

I tested it on 4 processors as well as serial mode but it stops with the 
above error both ways.
