No, id did not, but I did not modify the versions.
From what I understood from yoyur explanations, I would try (modifications in ** bold **):
pkgname=conky-cairo
**pkgver=1.12.2**
**pkgrel=1**
pkgdesc='conky - built for nvidia - Just change one variable to build the git version - defaults to release version.'
url='https://github.com/brndnmtthws/conky'
license=('GPL3' 'BSD')
arch=('i686' 'x86_64')
replaces=('torsmo' 'conky')
conflicts=('conky')
provides=('conky')
**SNIP**
