Ubuntu (percise): libopenblas-dev not available (Chromebook/Crouton)

Question

Laptop: Asus C100P Chromebook

OS: CromeOS with Crouton (chroot) Ubuntu Percise Ver 12.04.5 LTS

Trying to set up my Python environment with Numpy and Theano.

sudo apt-get install libopenblas-dev

output

Reading Package lists... Done
Building dependency tree       
Reading state information... Done
Package libopenblas-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'libopenblas-dev' has no installation candidate

there seem to be no resources to suggest that the BLAS package shouldn't be available. [How to install libopenblas-dev percise]

according to my limited knowledge [this] page would indicate that the ARM processor would have no problem with the package either, right?

is there another way to install this package?

EDIT: The packages i was trying to install (numpy and theano) seem to work without solving this problem. Could BLAS be base/native functionality in ChromeOS? (will keep question open in case libopenblas-dev may be an issue for future users)
