Comment(by mdgabriel):
@pcapriotti: I would by happy to supply more information, but I am not
sure what to supply that would be helpful. Can you give me some guidance?
What I can tell you is that 7.0.4 was a built by me. Version 7.4.1 is
available for Ubuntu 12.04 LTS. In both cases, I compiled the package
vector using cabal with the options -O and -p.
I will verify my installation to make sure I do not make a mistake and
have an unoptimized Data.Vector for 7.4.1.
