Yes ... by giving more attention to the error message ... :P

The error message is not "cannot load any file in <dir>" but

/tmp/orogen_pending_loads20120925-9449-1b0qort-0:1:122: error:
/home/build/jenkins/workspace/AvalonBootstrap/FLAVOR/next/label/DebianUnstable/dev/install/include/avalon_base:
No such file or directory
/home/build/jenkins/workspace/AvalonBootstrap/FLAVOR/next/label/DebianUnstable/dev/install/lib/ruby/1.8/typelib-gccxml.rb:600:in
`gccxml': cannot load one of the header files

  

In other words, gccxml has been instructed to load 
install/include/avalon_base as if it was a header (which it is not).

There is indeed a bug in orogen. My guess is, you do:

   import_types_from "avalon_base"

In which case orogen looks for either a header with that name, or 
another orogen project with that name. The test is too lax and will 
accept directories (it should only accept files).

In other words:

   -  I guess that you are missing a dependency on the avalon_base 
orogen project
   - oroGen should only look for files, not directories
