Plugins not loaded from OSX bundle

[eranon]

Hello. Some month ago I succeeded to build, then bundle C::B SVN under OSX 10.6. Today, I'm trying to renew with the current SVN head. All sounded right (close to right since I experienced an error like "C++ compiler cannot create executables", but solved it) during building and bundling (using the same process as the one I did in the past, inspired by the wiki and Apple documentation), but when I run this fresh codeblocks.app, CodeBlocks is launched without plugin.

The C::B log window shows :

Code Select Expand

Scanning for plugins in /Users/eranon/Library/Application Support/codeblocks/share/codeblocks/plugins
Loaded 0 plugins
Scanning for plugins in /Users/eranon/Downloads/From_SVN_Repo/Codeblocks/codeblocks.app/Contents/Resources/share/codeblocks
Loaded 0 plugins

I've checked my codeblocks.app tree and "codeblocks.app/Contents/Resources/share/codeblocks" well contains the zip files about plugins. Also, I've compared the tree with the official 12.1.11 binaries and it seems to look identically.

So, what to do next ? I've maybe missed a point (or forgotten an OSX specificity) but I don't see what...
Do you have an idea ? Is there a way to get more verbosity about the reason why of this plugins loading failure ?

EDIT : I'm seeing a shell script called "src/mac_pack". So, I've taken a try and it claimed about a lot of missing files. Then, I've tried to run "/src/update" before, but it claims about missing files too (e.g. "devel/*.dylib"). Well, it sounds the OSX process to succeed to get a full working codeblocks.app is unclear for me. What should I do to use "src/mac_pack" ?
