Our gzip(1) has a trouble unpacking lokigames/idsoftware etc archives (a shell script and tar.gz in one file) making these packages fail in pkgsrc. The main trouble is that it's not gzip(1) itself and probably not libz either that causes the problem, but something else. I have exactly the same problem with GNU gzip from pkgsrc in DragonFly, but GNU gzip works just fine with these archives on every other platform I have access to. Our tar doesn't have problem either with these files (not using gzip, but libz directly).
Finding out what exactly causes it is beyond my skills at the moment ... The testcase: $ fetch \ ftp://ftp.estpak.ee/pub/FreeBSD/ports/distfiles/linuxq3apoint-1.32b.x86.run $ sed '1,265d' linuxq3apoint-1.32b.x86.run | gzip -cd > /dev/null gzip: input not gziped (MAGIC0) $ $ sed '1,265d' linuxq3apoint-1.32b.x86.run | /usr/pkg/bin/gzip -cd \ > /dev/null gzip: stdin: unexpected end of file $ $ sed '1,265d' linuxq3apoint-1.32b.x86.run | /usr/bin/bsdtar zxfO - \ > /dev/null $ -- Hasso Tepper
