/usr/local/bin - all my files were removed

[saka]

Hello,

I have a macbook pro.

Before a few days I had a look on my /usr/local/bin folder and it was empty!
There also were problems in booting - blue screen.
I solved it but the bin folder is still empty.

How can I restore it?
I did installation of the OSX 10.6.8 (my version) and later I upgraded to mountain lion but the folder is still empty.

Any suggestions?

Thanks,
saka

The least-messy and preferred way would be a fresh ML install.

Manually replacing those binaries from another Mac installation could result in strange issues.
