Description of problem:


Version-Release number of selected component (if applicable):
# rpm -q scl-utils
scl-utils-20130529-17.el7_1.x86_64

Tested on CentOS Linux release 7.1.1503 (Core).

How reproducible:

$ ruby -v
ruby 2.0.0p598 (2014-11-13) [x86_64-linux]
$ scl enable rh-ruby22 bash
$ ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux]

Password: 
# echo $X_SCLS
rh-ruby22
# ruby -v
ruby: error while loading shared libraries: libruby.so.2.2: cannot open shared object file: No such file or directory
# scl enable rh-ruby22 bash
# echo $X_SCLS
rh-ruby22
# echo $PATH
/opt/rh/rh-ruby22/root/usr/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/vagrant/.local/bin:/home/vagrant/bin
# echo $LD_LIBRARY_PATH

# ruby -v
ruby: error while loading shared libraries: libruby.so.2.2: cannot open shared object file: No such file or directory


Steps to Reproduce:
1. enable collection
2. change user
3. try to use the collection


Additional info:

It seems that some ENV variables remains when changing users but some not. Because of that enabled collections are broken and enabling them again does not help.
