I have gentoo on my RPI3. I am running into issues with the install. I cannot emerge anything and some commands will not run. When I emerge I get warnings that bzip2 cannot be found. However I see the file is /usr/bin. Here are some examples

localhost ~ # bzip2
-bash: /usr/bin/bzip2: No such file or directory
localhost ~ # whereis bzip2
bzip2: /usr/bin/bzip2 /bin/bzip2 /usr/share/man/man1/bzip2.1 /usr/share/man/man1/bzip2.1.gz
localhost ~ # file bzip2
bzip2: cannot open `bzip2' (No such file or directory)
