[gentoo-dev] repoman - I cannot handle it...

Hello fellow developers,

I have a problem with repoman. I keep breaking the dependency tree. Jabub 
knows what I'm talking about. Latest examples are bugs #196470, #196472 and 
#196474. On a side note I actually don't want to break the dependency tree...

Attached are the scripts I use to commit packages stable/unstable. Somewhere 
must be a bug!

'name_split.cpp' splits a package name like sys-devel/gcc-4.1.2 into category, 
package name and version number. It's done in c++ as that's the only language 
I do more with than 'hello world' programms. Not much more, just more. ;-)

'mp.sh' is the script which calls name_split, repoman etc. It's pretty 
straight forward and only does the things I would also do by hand.

So if I want to mark for example sys-devel/gcc-4.1.2 stable on ppc64 I call 
mp.sh like this: mp.sh ppc64 sys-devel/gcc-4.1.2 "Stable on ppc64"

If someone has a hint where the problem is, I would really appreciate that.

Best regards,

-markus

P.S.: yes, I do 'cvs up' on the whole tree, before starting a commit.
