[Evolution] error compiling multisync

[gargarmel <gargarmel gmx net>]

hi,

i'm trying to sync my phone with evolution.
compiling http://multisync.sourceforge.net/ complains about missing
ical-evolution library:

checking for icalcomponent_as_ical_string in -lical-evolution... no
configure: error: You must have the ical-evolution library installed
(i.e. Ximian Evolution). MultiSync is not yet configured to use the
standard ical library..

i am running evolution from the debian-sarge packages (version 1.0.5)

what's wrong here? will i be lucky installing version 1.2?

kind regards, gargarmel.
