Node.js and npm.. tar not found

[mb0]

I am trying to install socket.io. I have installed node using ab, and tried to install npm with 'curl http]://npmjs.org/install.sh | sh'
This complained 'No suitable tar program found'.

Can anyone suggest how i can fix / work around this?
Thanks.

the base system uses busybox tar - maybe loading the gnu tar extension might help?

That appears to have worked, thank you!

came across this issue again and got fairly stuck.. so for future reference heres the method;

install *all* of the following with ab: nodejs, bash, tar, curl, make and npm.
After installing all of these, then run `sudo curl http://npmjs.org/install.sh | sh` and then it should work.

bash, tar, make and curl extensions can be removed later if not needed.

e: also seems to need to be ran as root, 'sudo' doesn't work reliably.
