--------------------------------------------

PCRE could not be downloaded

Nginx requires PCRE for its rewrite module, so this installer will attempt to
install Nginx without the rewrite module.

If you want to make use of Nginx's rewrite module, please install PCRE manually
by downloading it from:

  http://www.pcre.org/

Yes, the solution is to manually install PCRE:

sudo aptitude install libpcre3 libpcre3-dev

There's a related discussion on the Passenger mailing list: PCRE version no longer on ftp site: breaks installer
