[oe-users] mysterious .debug dirs

[Star Glue]

Hello list,
I'm trying to compile Pure Data Anywhere (an audio application) with OE, 
but the Quality Assurance complains at the do_package task, saying :

ERROR: QA Issue: non debug package contains .debug directory: ...

This is followed by the path of the .debug dir.

I cannot find in the source of Pure Data any line that create those 
.debug dirs (no makedir command ...)
I think I don't need them but while I don't know how they are created, I 
can't remove them.
Any help would be appreciated.
regards,
Hal
