Cannot install Pipeline Pilot on Ubuntu (installer thinks my OS is 32 bit)

Hello all,

I'm trying to carry out the install of Pipeline Pilot on my Ubuntu server machine but I don't get very far because upon running ./sciinstall I get the error:

“It appears that you are attempting to install 64-bit version server on a 32-bit system.

Exiting installation.”

This is strange, because my Ubuntu installation is 64 bit.
