We want people to be able to install ngx_pagespeed like any other nginx module. If PSOL were a full-fledged library with a stable interface we could simply say "install PSOL" which might be as easy as `apt-get install psol-dev`, but it's not. Instead we directly include a precompiled binary library along with its headers. By building the binaries on something sufficiently old (Centos 5.4) they should work pretty much everywhere someone might think to run ngx_pagespeed, but building from source is still a documented option if they don't. Headers and binaries are from trunk of r2338, as documented in the READMEs.
