While solving this issue today I crashed my system. I again installed
ubuntu 14.04 LTS .

I followed following step.

$ sudo apt-get update

I already has python so I didnt install intentionally. Then I did

$ sudo apt-get build-dep binutils gcc g++ gdb unzip git

I built rtems But got the same error "python missing or unusable ".
Then I just install $ sudo apt-get install python2.7-dev  This solved
my issue.I successfully built rtems. I guess issue was with i386
package and amd64. When I install python2.7-dev separetly it solved my
issue. Thanks for Jason and Joel to help me solve this issue.
