Installing boost library in /usr/lib: sudo ./boostrap.sh command not found

Question

I am trying to install the Boost C++ libraries using these instructions. This is using Ubuntu 10.10. I have unzipped the .zip file in /usr/lib, and cd'd to the boost_1_45_0 folder. I then run:

sudo ./boostrap.sh --help

And I get the following error:

sudo: ./bootstrap.sh: command not found

I don't understand why this is, as bootstrap.sh is clearly there in the current folder.

Is this because of the location I am installing to, or is it perhaps a command within bootstrap.sh that can't be found? It is a clean Ubuntu install so I am unsure as to why I am getting an error when following instructions so precisely.

On Unix, you really want to install from the tarball, not the .zip file. Tarballs preserve Unix permissions.

To make ./bootstrap.sh executable, issue chmod 755 bootstrap.sh.
