in QNX6.4.1 I install botstrap from binary and try to install some downloaded binary packages by pkg_add

#pkg_add -v /path_to_package_archive/name_of_archive

but had the problem

pkg_add: no pkg found for perl>=5.0
pkg_add: Can't install dependency perl>=5.0
pkg_add: 1 package addittion filed

and another time like

pkg_add: no pkg found for mktemp>=1.5
pkg_add: Can't install dependency mktemp>=1.5
pkg_add: 1 package addittion filed


Where my mistake? Thankg you.
