I'm not sure I understand the question. You ant to
know if the USE flags are different depending on which
machine the package is compiled on? Can you use the
above a variation of the above python script?

This works as expected. But a few more questions and this is more towards how portage handles the Padded data in the tbz2. Looking that the variables of IUSE and USE via print myuse and print myiuse I get : ['x86', 'X', 'aac', 'aalib', 'acl', 'acpi', 'aim', 'alsa', 'apache2', 'avi', 'bash-completion', 'berkdb', 'bitmap-fonts', 'bonobo', 'bzlib', SNIP .. 'kernel_linux', 'elibc_glibc'] ['mozilla', 'gtkhtml', 'debug', 'debug'] So if I understand it correctly, what is being done is XPAK will take the USE flags from the system which compiled the binary and then sort of make a comparison with the USE flags for that particular package and work from there?

Actually, revdep-rebuild doesn't care about USE flags or /var/db at all. All it checks is that the dynamic linking can be satisfied. With the exception of openoffice-bin, when revdep-rebuild indicates that it wants to rebuild a -bin package it means that the ebuild is potentially missing dependencies. The reason that I state potentially is that sometimes the libraries are placed in a non-standard place by the ebuild and revdep-rebuild is unaware of that non-standard location when checking the dynamic linking. I'm currently working on updating revdep-rebuild so that it will be easier to configure for both users and developers. Regards, Paul -- gentoo-user@gentoo.org mailing list
