Why must distcc be installed outside of chroot?

[mipimipi]

Hi,
I've just a (maybe stupid) question. I would like to use distributed builds via distcc in a chroot using clean-chroot-manager. It's clear that the distcc package must be installed in the chroot. But it seems that it also must be installed outside of the chroot. Why is that?
Thanks,
mipi

If you try to build without it, makechrootpkg will throw an error:

==> ERROR: Cannot find the distcc binary required for distributed compilation.
==> ERROR: Could not download sources.

Feel free to reopen if I am mistaken.

@graysky2: Thanks. I investigated that already. makechrootpkg does some consistency checks calling makepkg outside the chroot. This causes the error messages. I thought you know why that is done that way. I might ask the Arch Linux guys.
