Is this perhaps a pacman issue? The epoch versioning is our own in house versioning schema which shouldn't affect pacman's ability to resolve this dep. 1.99 is 1.99 regardless of whether its labelled by us as 1.99 or 1:1.99. An epoch value should be considered very much different from the pkgrel, which must be honored in a depend.

I have the same problem here. I talked about it in archlinux forums. Will "blacklist" grub2 until this issue is fixed.

Could it be that the package requires "grub2-common=1.99", when the latest testing version is "1.99-2" (note the "-2")?

The 1.99-2 (pkgrel=2) has worked before with 1.99~rc1 and 1.99~rc2 packages. Its definitely the epoch value which is creating the problem. For some reason pacman does not consider grub2-common-1:1.99-2 as being equal to grub2-common=1.99 .

From the PACBUILD(5) manpage (http://www.archlinux.org/pacman/PKGBUILD.5.html):

"epoch:
... the default value if left unspecified is 0."

That might be taken slightly out of context, but it seems like pacman would read "grub2-common=1.99" as "grub2-common=0:1.99" if no epoch was specified, and since version comparison would treat 1:1.99 as a higher version than 0:1.99, it probably wouldn't consider them equal.

extra/grub2-bios 1:1.99-3
