[Rd] unable to compile mgcv

[Chuck White]

Hello -- I am trying to compile R-2.9.2 on IBM Power5 machine with AIX 5.3.  I have posted three previous posts. Over time I have made significant progress towards getting a successful build. I am now getting the following error:

==========================================================

Stop.

Initially I had mgcv 1.5-5 and I downloaded mgcv 1.5-6 and tried again. I get the same error.

I would really appreciate any help with this.

Thanks.
