No you're not:

It is picking up the system toolchain of your OS (RHEL 7?), which probably
gives you a glibc 2.17, which won't work with that 2.22 symbol something
wants (you didn't show what, or how it got that 2.22 version; either way,
you don't want to use 2.17 (or 4.8.5) when developing new code).

Probably if you make everything find the newer toolchain all will work
well.  It's either a configuration problem on your side, or one of the
tools you're trying to build is misbehaving.

Good luck,
