Compiling Ruby/SerialPort on OSX (Intel)

has anybody had any luck in compiling ruby/serialport ( for an intel based osx? I try to run extconf.rb as per the instructions, but get an error message:

"checking for OS... darwin checking for termios.h... no *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options."

i have googled extensively, but haven't found any info about this. it would be interesting to know if this applies to my machine only, or if it is a general problem. (btw, xcode is installed on my computer)

any help is much appreciated, helge

I have had no problems on my non Intel OS X box.

Can you tell me if you have installed the xcode developer tools that are required for the make to work.

The xcode tools are available on your OS X install disk.

I've also installed this both on my newer Intel MacBook Pro and my old PPCBook. Never had any problems with it -- though the rubyforge page is not necessarily too reassuring on the subject of Mac compatibility and you definitely need to have the Developer Tools installed. I know they're available as a free download from Apple if you can't find your OS install disk...
