Gigantic Linux Package

I followed this guide: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

Everything seemed to work fine, until I checked the packaged files in the staging directory. The LinuxNoEditor directory has a size of aroung 1GB, while the WindowsNoEditor directory, which was created by packaging the exact same project is only 460MB.

Is there any way to reduce the size of the Linux-package? And if not, is there any reasonable explanation as to why the Linux-package is more than double the size?

Thanks in advance,
