Error installing python-snappy: snappy-c.h: No such file or directory

I am using amazon ec2 ubuntu 11.04 server

 sudo pip install python-snappy 

also I tried to downloaded package and entered "sudo python setup.py install"

I got the error:

  running build
  running build_ext

  gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c snappymodule.cc -o build/temp.linux-x86_64-2.7/snappymodule.o

  snappymodule.cc:31:22: fatal error: snappy-c.h: No such file or directory
  compilation terminated.
  error: command 'gcc' failed with exit status 1

How i could get rid of this error?
