[Scip] SCIP problem installation on Mac OS

[Paolo Lazzeroni]

Hi all,
I was an old user of SCIP on linux OS platform (ubuntu 10.04 release) 
and one week ago I changed my pc with a mac. Now I would like to keep 
the SCIP toolbox also on my new mac but I have encountered some problem 
during the installation. In fact following the instruction shown in the 
"INSTALLL" file inside of  "ziboptsuite-2.0.0" folder, the first step is 
to enter the command "make" (or "sudo make") in to the command line 
pointed within the ZIB folder ("ziboptsuite-2.0.0" ). But the command 
doesn't produce any effect exept for this one:

-bash: make: command not found
   sudo: make: command not found (using sudo command)

Can someone help me? Is there someone that has encountered the same problem?

Thank you.

Paolo
