[OS X TeX] Building Asymptote with OpenGL support

I have succeeded to compile and install Freeglut on 10.5 but I used  
some workarounds.
When configuring, you should have a warning like this:
checking GL/gl.h usability... no
checking GL/gl.h presence... no
checking for GL/gl.h... no
Freeglut looks for some libraries it doesn't find. I made a symlink  
in /usr/local/include targeting the GL directory which is in  /usr/X11/ 
include.
After that reconfigure and now you should have:
checking GL/gl.h usability... yes
checking GL/gl.h presence... yes
checking for GL/gl.h... yes
Then you can do a make which ends with an error complaining about  
"long long" (I don't remember what exactly) in the Xmd.h  file which  
is in /usr/X11/include/X11.
Go to the line 155 (I'm not sure!) and comment it. Save and do a make.  
It should go to the end without any problem then sudo make install.  
Don't forget to uncomment the line in Xmd.h and save.

I configured Asymptote 1.49 without extra options but the making  
process ends with an error I can't solved.
Nevertheless, I installed Asymptote and it works but not in all cases.
