When I try "make" in devel/pango (pkgsrc-2006Q1, NetBSD/i386-2.1)
I get the following continuously looping autoconf warning...

/bin/sh ./config.status --recheck
cd . && /bin/sh ./config.status Makefile 
config.status: creating Makefile
cd . && /bin/sh /usr/src/pkgsrc/devel/pango/work/pango-1.12.0/missing --run autoconf

I have autoconf-2.59nb2 built from the same pkgsrc.
