You shouldn't need those extra libraries. Make sure you have compiled Gambit as c++ code (some option in configure).
Thank you again, I didn't know that gambit could be compile with g++...! But, as I try to compile it with g++, I get an error at compilation. I'm now compiling the version 4 beta 22. I tried to compile gambit version 4 beta 20 and it worked fine... Here is what the error I got:

I would prefer to install gambit 4 beta 22 instead of beta 20 (to be able to use snowfort), am I the only one which this problem occured?
Thank you very again for your help!

I suggested that David dirtily comments the line (537) in OS.h that does
#ifdef USE_environ extern char **environ; #endif
for it is a bad idea to modify unistd.h (that declares that same variable line 475 under the __USE_GNU #ifdef statement).
Looks like it compiled well. If this inserted a big bug somewhere, I am sure he'll be happy to ask you for another solution :)
