Trying to build gpg on AIX 6.1

[Dirk Walter]

Hello all, I am trying to build gpg on an AIX 6.1 machine and while
some people have reported success I can't even get configure to
successfully run. The problem seems to be with the -V flag which takes
arguments but none are provided in the configure script. I have
included the part of the log I believe are relevant.

I get the same regardless of if I run plain "./configure" or
"CFLAGS="-g -O2 -mcpu=powerpc" ./configure" as I have read elsewhere.
What am I doing wrong?
