PFreeze appears to leave out panda3d.core, yet it's included

Thank you for the help. However, this didn’t appear to work, and still returned no module named core. The linking works, but I needed a custom panda that has support for Astron. So, I built it and installed it. I tried using pfreeze and freezetool from 1.10 with the Astron panda3d, and that kept returning errors. So, I reinstalled it and tried your suggestion, and it didn’t work.
