xrc files not installed when --enable-debug is not set(?)

Hi,

here is my stupid question of the day:
is it normal that pgadmin/ui/*.xrc files are not installed if
"--enable-debug" is not set? I thought these files were mandatory for
the app to appear (if not, can someone explain what role they have in
the app?).

It appears to be disabled in pgadmin/Makefile.am:
 64 if BUILD_DEBUG
 65 nobase_dist_pkgdata_DATA = $(TMP_ui)
 66 endif

If normal, can I safely ignore these files for the packaging stuff?

Regards,
Raph
