Excuse me, there are some trouble when i install this gem in my macbook with OX EL Capitian. I has set the environment variables as follow:

But it's seem that the DYLD_LIBRARY_PATH variable is not working.

extconf failed, exit code 1

And the environment variables in pry:
[1] pry(main)> ENV['ORACLE_BASE']
=> "/usr/local/oracle"
[2] pry(main)> ENV['ORACLE_HOME']
=> "/usr/local/oracle/product/instantclient_11_2"
[3] pry(main)> ENV['DYLD_LIBRARY_PATH']
=> nil

as you can see, the DYLD_LIBRARY_PATH variable is not working.
I was confused by this problem for several days。
Thanks for your help

Firstly, could you check the environment variable in shell?

$ env | grep DYLD_LIBRARY_PATH

If it is set, did you run ruby via a setuid or setgid program?
DYLD_* environment variables are unset for security reasons if a program is setuid or setgid.

Thanks !
I check the environment variables and DYLD_LIBRARY_PATH is not set.
It was working fine in Yosemite, but after upgrading to EL CAPITIAN, it cant not work any more!!!

I closed this issue because this isn't a ruby-oci8 issue.

This is an OS issue. DYLD_ environment variables are unset in some cases
in the latest beta version.

DYLD_ environment variables are unset by design on OS X 10.11 El Capitan.
Use ruby-oci8 2.2.0 and look at http://www.rubydoc.info/github/kubo/ruby-oci8/master/file/docs/install-on-osx.md.
