QT 4.5 + .config problem with Basic XLib?

[qoo]

hello,

installing X11 and after

cd /tmp
gunzip qt-x11-opensource-src-4.5.2.tar.gz # uncompress the archive
tar xvf qt-x11-opensource-src-4.5.2.tar # unpack it

and

cd /tmp/qt-x11-opensource-src-4.5.2
./configure

I'll get

Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /tmp/qt-x11-opensource-src-4.5.2 /mkspecs/linux-g++.

and

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily
unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

-> .config stops and can't make the build.

Haven't got those msg before...
So, what I'm doing wrong?

-cheers

Close the application (a package manager?) that has locked the package database.
