Bug 746778

Description of problem:

Arduino sketches will not compile using the IDE.

Version-Release number of selected component (if applicable):

arduino.noarch 0022-4.fc15

How reproducible:

This happens 100% of the time.

Steps to Reproduce:
1. Open Blink example
2. Click the "Verify" button or press Ctrl+R
  
Actual results:

Expected results:

Sketch compiles without error.

Additional info:

These are the actual commands being executed to compile the sketch:

One solution seems to be to downgrade avr-gcc and avr-gcc-c++ packages.
