In attempting to compile Varnish from source, I am running into a number of issues related to Bitnami's custom $PATH settings, namely that the compiler cannot find the correct pkg-config location ("configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config."). I attempted to set 'PKG_CONFIG_PATH=/opt/bitnami/common/lib/pkgconfig' but it still gives the error. Am I overlooking something, or is there a more ideal way to install Varnish?
I'm using an EC2 AMI (bitnami-drupal-7.18-0-linux-ubuntu-12.04.1-x86_64-ebs)
