From 5.2.3.1. PORTREVISION:

PORTREVISION is a monotonically increasing value which is reset to 0 with every increase of DISTVERSION, typically every time there is a new official vendor release. If PORTREVISION is non-zero, the value is appended to the package name. Changes to PORTREVISION are used by automated tools like pkg-version(8) to determine that a new package is available.

Set PORTREVISION to 0 instead of 1, reported by mat@
