Installing snap on Arch

I got an error when following the instructions to install snap on Arch Linux from https://snapcraft.io/install/multipass/arch#install

Perhaps you should add the directory containing `libseccomp.pc'
to the PKG_CONFIG_PATH environment variable

libseccomp was installed on my system:

└─> pacman -Q libseccomp
libseccomp 2.5.4-1

But it wasn't under under PKG_CONFIG_PATH, which was set to /opt/local/lib/pkgconfig.

└─> ls -Alh /opt/local/lib
ls: cannot access '/opt/local/lib': No such file or directory

It was under /usr/lib/pkgconfig:

└─> ls /usr/lib/pkgconfig/ | grep libseccomp
.rw-r--r-- root root 1009 B  Fri Apr 22 01:56:45 2022 libseccomp.pc

So I used a custom PKG_CONFIG_PATH with the makepkg command:

PKG_CONFIG_PATH=/usr/lib/pkgconfig makepkg -si

And the command ran successfully
