>Description:
pkg-config in current miscompiles on slackware 13.0. A huge amount of pkgsrc 
programs call pkg-config during configuration phase.

Here is the configure output from x11/libXau - similiar output exists for a 
huge number of other packages during configuration phase:

configure: error: Package requirements (xproto) were not met:

/tmp/current/x11/libXau/work/.tools/bin/pkg-config: line 5: 18232 Aborted       
          
PKG_CONFIG_LIBDIR=/tmp/current/x11/libXau/work/.buildlink/lib/pkgconfig:/tmp/current/x11/libXau/work/.buildlink/share/pkgconfig
 PKG_CONFIG_PATH= /usr/current/bin/pkg-config "$@"

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XAU_CFLAGS
and XAU_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
