>Description:
pkg_add -f doesn't force installation of package even if dependencies are not 
found/installed. 

x350# pkg_add -f ./scmgit-base-1.6.3.3.tgz   
pkg_add: Warning: package `scmgit-base-1.6.3.3' was built for a platform:
pkg_add: NetBSD/i386 5.0 (pkg) vs. NetBSD/i386 5.99.17 (this host)
pkg_add: no pkg found for 'tk>=8.4', sorry.
pkg_add: Can't install dependency tk>=8.4
pkg_add: 1 package addition failed

pkg_add(1) says:

 -f      Force installation to proceed even if prerequisite packages are
             not installed or the install script fails.  Although pkg_add will
             still try to find and auto-install missing prerequisite packages,
             a failure to find one will not be fatal.  This flag also over-
             rides the fatal error when the operating system or architecture
             the package was built on differ from that of the host.


>How-To-Repeat:
Try to install some package with not resolved dependencies.
