Compilation problems with IBM mpxlf90

[a.c.padilha]

I have received this message when trying to compile the vtstcode with Vasp 5.3.3:

1501-510 Compilation successful for file opt.f.
/usr/ccs/lib/cpp -P -DHOST=\"SP2/3/4\" -DMPI -DPGF90 -DUSE_ZHEEVX -DCACHE_SIZE=32768 -DNGZhalf main.F >main.f
mpxlf90 -qarch=pwr7 -qcache=auto -qinitauto -qintlog -c main.f
"main.f", line 2227.16: 1513-029 (W) The number of arguments to "densta" differs from the number of arguments in a previous reference. You should use the OPTIONAL attribute and an explicit interface to define a procedure with optional arguments.
"main.f", line 2822.45: 1513-061 (S) Actual argument attributes do not match those specified by an accessible explicit interface.
** vamp === End of Compilation 1 ===
1501-511 Compilation failed for file main.f.
make: 1254-004 The error code from the last command is 1.

The compiler version is:
IBM XL Fortran for AIX, V13.1 (5724-X15)
Version: 13.01.0000.0005

I haver followed all the steps in the download section, but cannot get the code to work... If someone could help me with this, i would really appreciate.

This does not appear to be related to the vtstcode.
