Thanks Stefen - now it works fine, but I got a little bit confused with the messages. I did

dpkg -i --force-overwrite libxcursor-dev_1.0.2-2_i386.deb

it showed me the following message:

dpkg: dependency problems prevent configuration of libxcursor-dev:
libxcursor-dev depends on libxcursor1 (= 1.0.2-2); however:
Package libxcursor1 is not configured yet.

So I installed libcursor1

user@Linuxbox:/var/cache/apt/archives# apt-get install libxcursor1
Reading Package Lists... Done
Building Dependency Tree... Done
libxcursor1 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
408 not fully installed or removed.

It sounds funny, but now everything works fine
