Error compiling AppimageKit for Arch Linux

Hi!

I'm trying to generate a PKGBUILD to compile AppimageKit on Arch Linux via makepkg script, without installing appimaged daemon (thus, users must run appimage files from file manager or console).

I've found mksquashfs errors, that aborts compilation:

Scanning dependencies of target mksquashfs
[ 11%] Creating directories for 'mksquashfs'
[ 12%] Performing download step (git clone) for 'mksquashfs'
Cloning into 'mksquashfs'...
Note: checking out '5be5d61'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

HEAD is now at 5be5d61 pseudo.c: Fix pseudo format error message

What can I do to solve this?
