Problem compiling gtexinfo on Interix 6.1 (64 bit)

["Carson M. Chittom" <cmchittom%att.net@localhost>]

I don't know the first thing about programming, so I'm probably missing 
something obvious--apologies in advance.

Iâm trying to use pkgsrc on Windows 7/Interix 6.1 64-bit (amd64).  Since I'm 
a stable kind of guy, I downloaded the 2010Q4 tarball and started the pkgsrc 
bootstrap, which failed with

ar: Either the AR_LIBRARIAN environment variable must be set
ar: or you must include the directory containing 'lib.exe' in PATH

I found a couple of threads from this list from 2009 which suggested that 
the issue was due to some 32 vs 64 bit stuff and configure not correctly 
figuring out which ar to use.  Following something else I found online, I 
set AR=/opt/gcc.3.3/bin/ar and that let the bootstrap complete.  I then 
tried to install devel/scmcvs--which worked fine until the dependencies got 
to devel/gtexinfo, which failed with the same error as the bootstrap did 
initially.  I made sure AR was still set, did a bmake clean-depends in 
devel/scmcvs, and tried again with no joy.  Setting AR in 
/usr/pkg/etc/mk.conf had no luck either.

So I downloaded the current tarball, re-boostrapped, and tried again.  Same 
thing.  I found a bug report that was closed February 6, 2011, in which 
devel/gtexinfo failed to link on Interix 6.1, so I cvs up'd to the latest as 
of today and tried again.  Still the same error.

Can anybody point me in the right direction?  I'm under the impression that 
lots of packages depend on texinfo, so I think I need to fix this before I 
go any further.  As I said, I'm no programmer, but I'll be glad to test 
anything sent me.
