Linux buildhost.domain.pl 2.6.18-194.8.1.el5 #1 SMP Thu Jul 1 19:04:48 EDT 2010

>Description:
Package built under Linux has OS_VERSION stripped at first '-': for example 
OS_VERSION '2.6.18-194.8.1.el5' is shortened to '2.6.18'. pkg_add has function 
for this (normalise_platform() in pkg_install/files/add/perform.c) but at this 
moment function is used only for DragonFly and FreeBSD, so pkg_add produces 
annoying comments, for example:

pkg_add: Warning: package `p5-HTML-Parser-3.65' was built for a platform:
pkg_add: Linux/x86_64 2.6.18 (pkg) vs. Linux/x86_64 2.6.18-194.8.1.el5 (this 
host)

To rid this we need only one, small change in configure.ac, see below.

Sample outputs from uname -r from various distros:

Ubuntu 10.04: 2.6.32-22-server
Fedora 13     2.6.33.5-124.fc13.i686.PAE
RHEL   5.3    2.6.18-194.8.1.el5
Denian 4.x    2.6.18-6-686
Debian 5.x    2.6.26-2-686

>How-To-Repeat:
Build and install any package under Linux.
>Fix:
Change, in pkg_install/files/configure.ac

from:

case $host in
*-*-dragonfly* |*-*-freebsd*)
        AC_DEFINE([NUMERIC_VERSION_ONLY], [1], [Defined when to retain only the 
numeric OS version])
        ;;
esac

to:

case $host in
*-*-dragonfly* |*-*-freebsd*|*-*-linux*)
        AC_DEFINE([NUMERIC_VERSION_ONLY], [1], [Defined when to retain only the 
numeric OS version])
        ;;
esac

and re-build 'configure'.
