Hello!
in a brand new environment (CentOS 6.7 and CentOS 6.9), I’m able to install meteor as root, then as regular user run meteor --version and immediately I get this error
/home/juanpa/.meteor/packages/meteor-tool/.1.5.2.ecibw9++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/bin/node: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by /home/juanpa/.meteor/packages/meteor-tool/.1.5.2.ecibw9++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/bin/node)

one more thing I’m installing devtoolset-2-gcc devtoolset-2-binutils devtoolset-2-gcc-c++ from http://people.centos.org/tru/devtools-2. This used to fix this problem but not anymore 
how can I fix this problem??
thanks in advance
