Sprite compilation error

Im running the arduino software version 11 under ubuntu linux (hardy heron). upon startup of the software, i receive the following errors:

Sprite.cpp:20:20: error: stdlib.h: No such file or directory
In file included from Sprite.cpp:24:
Sprite.h:23:22: error: inttypes.h: No such file or directory
In file included from Sprite.cpp:24:
Sprite.h:30: error: 'uint8_t' does not name a type
Sprite.h:31: error: 'uint8_t' does not name a type
Sprite.h:32: error: 'uint8_t' does not name a type
[...]

there are many more errors, but i believe they all stem from this first one. i can compile a simple helloworld program that includes stdlib.h just fine, so im not entirely sure why arduino is having trouble.

ive reinstalled the following, but it makes no difference: gcc g++ libc6 libc6-dev make build-essential

how should i troubleshoot further?

thanks

Strange thing... Can you compile a program with the Sprite library included ? Have you tried just reinstalling the environment ?

Did you install the avr version of libc?

FYI - I had the same issue with arduino 16 under Ubuntu 9.0.4 Installing avr-libc(via Synaptic) fixed everything - now get clean launch - no errors
