[aur-general] Building a git version of a package already present in the official repositories

[Muflone]

Hello

In the AUR section of the Arch Packaging Standards guide [1] we can read 
that a package must not build any of applications in the official 
repositories.

At the moment the extra/strace 4.7-1 package uses the most updated 
released version of the application but the current version has a defect 
with custom kernel version numbers (eg. the 3.3-pf) which renders the 
tool unusable at all.
Such bug has been fixed in the git repository [2] but the author has not 
yet released an updated version.

Would be allowed to build a strace-git package to always pick the most 
recent version from the git repo, even if it builds a binary application 
present in the official repos?
What guidelines should be followed to avoid conflicting packages?

Thanks in advance
