Re: [gentoo-dev] Difference between PDEPEND and RDEPEND?

[Sergey Kuleshov]

Hi Alexander,
Did some searching through emerge sources and checked that by small 
test. PDEPEND will _not_ reemerge a package if it's already installed. 
All it does is that it says: "should we wish to emerge this package, we 
have to do aftewards". While RDEPEND obviously sais same this but " ... 
beforehand". So there is difference.

If you want to force use to reemrge some package afterwards, you might 
do some checks for package existence and ask user to reemrge it, but I 
don't this process can be automated in any way.
