>Description:
Original problem is that I cannot build and install x11-links package
under Linux. While 'bmake install' I get the following log
Note that in the following log awk failed but exit status of bmake is
zero :(

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
0 x11-links>bmake install

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Problem 1) exit status of awk is not checked by pkgsrc.
Problem 2) '(\${PKGBASE})' regexp is passed to awk.
           According to SUSv3 { and } symbols
           should be processed differently.

>How-To-Repeat:
/usr/bin/awk:
#!/bin/sh
gawk --posix "$@"

The try to build x11-links package
with X11_TYPE=native

>Fix:
Problem 2 is fixed with this patch:
