[gentoo-dev] environment variable GZIP cause pilot-link-0.9.6.ebuild (kde) to fail ?

[Michael Tartsch]

Hi

I had some trouble with kde dependance pilot-link. 
The environment variable GZIP=-9 cause the ebuild to fail.

---original problem----------------------------------------------
While building kde the dependency pilot-link-0.9.6 failed.
Without sandbox the following output was generated:

...
mkdir /var/tmp/portage/pilot-link-0.9.6-r3/image/usr/share/man/man1
mkdir /var/tmp/portage/pilot-link-0.9.6-r3/image/usr/share/man/man7
for m in ./man/*.1; do \
        /bin/sh ./libtool /bin/install -c -m 644 $m /var/tmp/portage/pilot-link-0.9.6-r3/image//usr/share/man/man1/`basename $m`; \
        /bin/cat $m | /bin/gzip > /var/tmp/portage/pilot-link-0.9.6-r3/image//usr/share/man/man1/`basename $m`.gz; \
done
/bin/install -c -m 644 ./man/dlpsh.1 /var/tmp/portage/pilot-link-0.9.6-r3/image//usr/share/man/man1/dlpsh.1
/bin/install -c -m 644 ./man/ietf2datebook.1 /var/tmp/portage/pilot-link-0.9.6-r3/image//usr/share/man/man1/ietf2datebook.1
/bin/sh: /bin/gzip: No such file or directory
...

After ebuild the /bin/gzip was missing and a file /bin/gzip.gz exists.
---analyze----------------------------------------------
After a lot of testing and reading I found out what has happened.

-  I have an environment variable for GZIP with defailt options:
   GZIP=-9
-  the Makefile of pilot-link contains the following segments:
   ...
   GZIP            = /bin/gzip
   ...
   for m in ${srcdir}/man/*.1; do \
       $(INSTALL_DATA) $$m $(mandir1)/`basename $$m`; \
       $(CAT) $$m | $(GZIP) > $(mandir1)/`basename $$m`.gz; \
   done
   If no environment variable is missing then the make variable seems 
   to be treated as local. 
   If an evironment variable GZIP exists then it is overwritten 
   and forewarded to the sub-shell.
   
-  The following command was called with 
   environment GZIP=/bin/gzip 
   cat somefile.1 | /bin/gzip > somedir/somefile.1.gz 
   gzip internally merges the $GZIP with the commandline and executes 
   "/bin/gzip /bin/gzip"
   uups
   
---Question-------------------------------------------------------------

What's wrong with my GZIP="-9" ?
