putting a dependency on libicu

[Riccardo Mottola]

Hi,

what's the best way to mark ICU as a dependency? the version is actually 
indifferent to me.

Currently I have in gnustep-base:
BUILD_DEP_PKGS = CSWgmake CSWgcc4objc CSWlibgnutls-dev CSWlibffi-dev 
CSWlibicu-dev
DEP_PKGS = CSWgnustep-make CSWlibgnutls28 CSWlibssl1-0-0 CSWlibffi5 
CSWlibicuuc52


which means a generic CSW provided ICU version and a specific 5.2 
runtime. What would you do?

when I build on unstable10s I get:
==> Verifying installed package CSWlibicu-dev: ok
==> Verifying installed package CSWlibicuuc52: MISSING

running pkginfo on unstable10s shows actually quite a maze of stuff:

it seems they are "split" and only for 4.6 there is a full version. What 
are the splits for?

suggestions?
