Gentoo Prefix on Debian

[ZekeMorrin]

Hello dear Gentoo community I have a question regarding using Gentoo prefix on other Linux environments;

I'm currently using Gentoo prefix on Debian Testing, I just want to know that if adding $PREFIX/usr/bin to my PATH is a very bad idea and horribly break stuff?
Because I really prefer using the programs installed through portage in my Debian environment without entering my $PREFIX/usr/bin folder manually unless it's breaking stuff.
Also, is it possible to add not the entire #PREFIX/usr/bin but single programs like lets say $PREFIX/usr/bin/npm and $PREFIX/usr/bin/node and such?
Second option would be more convenient if it's possible, and if so how can I do it?
Thanks!

Doing this will probably work some of the time in some cases, but in general I think it's likely to either not work properly or make the terminal unusable.
Your host system probably has a different glibc among other things, so running gentoo binaries against that will likely fail. If you edit the LD_LIBRARY_PATH to include the correct libraries then your host executables will be unhappy.

Thanks for the heads up LiamOS, so using the portage-installed programs inside prefix is the safest way, good to know!

The programs ought to work the same whether you cd into $PREFIX/usr/bin and use ./program versus if you invoke them by full path. Either way, the important thing is that they use the Gentoo libraries, not the Debian ones. That should be independent of how you invoke them, and of your $PATH.

If you want to use only select programs, you have two options. First, you could set up a directory such as ~/gentoo/bin, put that on your $PATH, and populate it with symlinks to the programs in $PREFIX/usr/bin. Second, you could define shell functions named npm(), node(), etc. that are implemented as:
