circular_buffer.so fails to load in 0.9.1 on OS X

[blalor]

config:

[stat_graph]
type = "SandboxFilter"
filename = "lua_filters/stat_graph.lua"

error output when starting hekad:

2015/03/19 06:50:14 Error making runner for stat_graph: Initialization failed for 'stat_graph': Init() error loading module 'circular_buffer' from file '/Users/blalor/tmp/heka/share/heka/lua_modules/circular_buffer.so':

Please provide the full configuration and the directory listing for the configured module directory.

Fwiw, I also ran into this issue and tried to get past it by using install_name_tool to update the lib path to my local build:

install_name_tool -change \
    /Users/rob/golang/heka/build/ep_base/Build/lua_sandbox/src/libluasandbox.dylib \
    /Users/pbooth/code/heka/build/ep_base/Build/lua_sandbox/src/libluasandbox.dylib \
    /usr/share/heka/lua_modules/circular_buffer.so

That changed the error to complain about _luaL_register being not found:

2015/12/24 16:50:18 Error making runner for FxaContentSignupMetricsCategorized: Initialization failed for 'FxaContentSignupMetricsCategorized': Init() error loading module 'circular_buffer' from file '/usr/share/heka/lua_modules/circular_buffer.so':

This is my config (I started off with the example from the docs, then modified it to add the filter that I'm testing):

[hekad]
maxprocs = 4

[LogstreamerInput]
log_directory = "/Users/pbooth/code/heka"
file_match = 'pb\.log'

[PayloadEncoder]
append_newlines = false

[LogOutput]
message_matcher = "TRUE"
encoder = "PayloadEncoder"

[FxaContentSignupMetricsCategorized]
type = "SandboxFilter"
script_type = "lua"
filename = "/Users/pbooth/code/heka/fxa_content_signup_metrics_categorized.lua"
ticker_interval = 60
preserve_data = true
message_matcher = "TRUE"

    [FxaContentSignupMetricsCategorized.config.services]
    marketplace = "0a42ac8a73be8762"
    hello = "a8b39c2b1cab722e"
    pocket = "749818d3f2e7857f"

The filter is fxa_content_signup_metrics_categorized.lua from this PR.

This is the directory listing for my module directory:

Any ideas what's up?
