Re: PAC library for develop version available

Hi,

I met an error message  while  "pack_install"-ing on SWI-Prolog V7.22
via GIT on Mac OSX Mavericks:

   % Contacting server at http://www.swi-prolog.org/pack/query ... ok
   Install [email protected] from https://github.com/samer--
   /prolog/raw/master/callgraph/release/callgraph-0.3.2.tgz Y/n? 
   dyld: lazy symbol binding failed: Symbol not found:
   _archive_read_support_filter_all

    Expected in: flat namespace

Rembering similar troubles in the past, I have edited the build file of the
pl-develop directory so that LIBRARY_PATH and CPATH does not refer to
/usr/lib :

# On MacOS you need this to get some libraries from Homebrew (not Macports)
if [ "`uname`" = Darwin ]; then
  export LIBRARY_PATH=/usr/local/Cellar/readline/6.2.4/lib:/usr/local/Cellar/gmp/5.1.3/lib:/usr/local/Cellar/libarchive/3.1.2/lib
  export CPATH=/usr/local/Cellar/gmp/5.1.3/include:/usr/local/Cellar/readline/6.2.4/include:/usr/local/Cellar/libarchive/3.1.2/include

After this change of the build file, the pack_install  has worked fine.
Excluding "/usr/lib/"  seems a typical workaround for Mac OSX
SWI-Prolog users. I am not sure  on the exact reason why
such editing works, but  I hope this note will be useful for mac prolog users
who is suffering from similar trouble.
