Installing gnupg 2.0.[89] on AIX 5.3

[REX NUFER]

I hope there is someone who can help me with the install problems I'm having.  I'm trying to install on an AIX 5.3 box.  Please CC me with any response.  I'm wondering if using an old version of gcc may be part of my problem. Thank you for any help you can provide.
First I tried to install gnupg 2.0.9 and got the following errors from the 'make check':

Making check in m4
Target "check" is up to date.
Making check in gl
        make  check-am
Target "check-am" is up to date.
Making check in include

Stop.

After making no headway with version 2.0.9, I backed up a version and tried to install 2.0.8.  I got a lot further in the 'make' before it finally errored.  The 'make' generated the following error:
Target "all-am" is up to date.
