Debian incompatibilities in make-driven installation

OS: Debian 13 (Trixie)

1. Debian traditionally does not (by default) configure primary user as a sudoer. Sudo is installed, however. In the make targets, `make deps` triggers failed permission warning.
2. `source ~/.profile` does not work in Debian; must be .bashrc
```
dwrob@rogue:~$ ls -al .profile
ls: cannot access '.profile': No such file or directory
```
