Cannot open libzmq.so.3 #39

While trying to build with 'rake' got following: /usr/bin/ruby22 -w -I"lib:test" -I"/usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib" "/usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib/rake/rake_testloader.rb" "test/**/test*.rb" /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require': libzmq.so.3: cannot open shared object file: No such file or directory - /mnt/disk/soft/rbczmq/lib/rbczmq_ext.so (LoadError) from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from /mnt/disk/soft/rbczmq/lib/zmq.rb:9:in rescue in <top (required)>' from /mnt/disk/soft/rbczmq/lib/zmq.rb:6:in<top (required)>' from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require' from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from /mnt/disk/soft/rbczmq/test/helper.rb:3:in <top (required)>' from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require' from /mnt/disk/soft/rbczmq/test/socket/test_dealer_socket.rb:3:in<top (required)>' from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require' from /usr/lib64/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from /usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib/rake/rake_test_loader.rb:10:in block (2 levels) in <main>' from /usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib/rake/rake_test_loader.rb:9:ineach' from /usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib/rake/rake_test_loader.rb:9:in block in <main>' from /usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib/rake/rake_test_loader.rb:4:inselect' from /usr/lib64/ruby/gems/2.2.0/gems/rake-10.4.2/lib/rake/rake_test_loader.rb:4:in `

Send/recv work after it. Tried on 'Gentoo' in case it matters.

Same issue on Arch, uname -a:

Linux starship 4.0.7-2-ARCH #1 SMP PREEMPT Tue Jun 30 07:50:21 UTC 2015 x86_64 GNU/Linux

Gist with log output.

It seems that the zeromq library built with rbczmq is not available on the library path, so that the libzmq.so.3 shared library is never linked with rbczmq_ext.so.

Prepending LD_LIBRARY_PATH shows this to be true:

The above PR only addresses running rake from the project root as outlined in the README, but at least it matches the intention to use the vendored, compiled libraries.

Can we compute the destination of ext/rbczmq/dst/lib within the GEM PATH? If this is possible then we could set an absolute directory to where the vendored libzmq, czmq libraries will be installed.
