I am very glad that you are interested in Gentoo builds! Some time ago, 
Chris and I on IRC have been addressing that Fat-Zer's overlay is not very 
well maintained, and that it would be good to set up an official one. For 
this reason, a new tde-packaging-gentoo repository was created, which 
contains a copy of the current Fat-Zer's repository.

https://mirror.git.trinitydesktop.org/gitea/TDE/tde-packaging-gentoo

The repository currently contains only the master branch, the r14.0.x 
branch has not been created yet. I don't know how Gentoo overlay works - 
whether it's possible to use branches. I don't even know if your plans are 
directed only to the latest master branch or whether you want to maintain 
a stable releases - currently r14.0.x branch. It's up to you.

Chris has some plans, you have some plans, it would be good if you can work 
together to make sure there is a well maintained official Trinity Gentoo 
overlay. That would be great.

That is a good question. I also think that only GPL remains valid for TQt.

Here are two numbers - the git repository versions and packages follow the 
TDE version numbering as a whole. However, the internal version number of 
the library is now 3.5.0. For deb packages, the package version is now 
14.0.7, where the so library version inside the package is 3.5.0.

msg2tqm (tqembed) is a tool for converting data, such as images, into C++ 
code that can be embedded as part of a binary. Unfortunately, I do not 
remember whether / where this tool is actually used. However, for deb 
packages it is also built as part of TQt.

It will be great if you can join your efforts with Chris and possibly other 
contributors. TGW is a great tool where you can discuss planned patches 
using issues and pull-requests. It could help you not give up and don't 
want to hide in a corner :)
