 Steps to reproduce:

 {{{
 $ export GZIP="-9"
 $ tar xvzf MacPorts-2.3.4.tar.gz -C /tmp/
 $ cd /tmp/MacPorts-2.3.4/
 $ ./configure && make
 }}}

 If the GZIP environment variable is set to a whitespace-separated list of
 options (as is documented on the man page for gzip), the configure script
 for MacPorts fails with this error:

 {{{
 configure: === extracting vendor/tcl8.5.15-src.tar.gz
 gzip: /usr/bin/gzip: unknown suffix -- ignored
 configure: error: tarball vendor/tcl8.5.15-src.tar.gz did not extract to
 vendor/tcl8.5.15/unix
 }}}

 Workaround:
 {{{
 $ unset GZIP
 }}}

 Diagnosis:
 The configure script (incorrectly) expects that if the GZIP environment
 variable is set, it contains a path to the gzip binary. This directly
 conflicts with the documented contents of the GZIP variable, as understood
 by /usr/bin/gzip. Unsetting GZIP shouldn't be necessary to build MacPorts
 successfully, since it shouldn't overload the contents of an existing
 variable.

Comment (by ryandesign@…):

 Duplicate of #43245 I think. This should have been fixed in r125362. You
 can check whether MacPorts trunk (version 2.3.99, which will one day
 become 2.4) fixes it; it should.
