Arch Linux

VCS sources are specified like this:
[folder::][vcs+]url[#fragment]
I'm trying to use a 'folder' like "pkg_group/pkg_xx" to store all the sources related to a package group into "${SRCDEST}/pkg_group/"
and encountered two problems:
1)
"${SRCDEST}/pkg_group/" directory is not created.
As a nasty workaround I've added "_make_dst_dir=$(mkdir -p ${SRCDEST}/pkg_group)" to the PKGBUILD
2)
In the source array there is a first BZR entry, several GIT entries and finally another BZR entry.
When makepkg is at "Extracting sources..." everything goes fine until the last source entry, which stops with the following error:
-> Creating working copy of pkg_group/pkg_xx bzr repo...
/usr/bin/makepkg: line 520: cd: pkg_group/pkg_xx: No such file or directory
==> ERROR: Failure while creating working copy of pkg_group/pkg_xx bzr repo
Aborting
I don't know why the first BZR entry works fine and the other one does not. I'll post my PKGBUILD if requested to reproduce the problem.
In any case I think a simple mkdir will solve it.

So, all in all, my feature request is to add proper support for subfolders in the VCS sources.
