Yes. You don't have a libgdk_pixbuf.so. I had the same problem on my computer, so I copied the file from a different 32 pc to there as there wasn't a package included with my distro that had that file in it for 32 bits.
/usr/lib/libgdk_pixbuf.so.2 is a 64 bit binary so it won't work.
Why aren't you using a 64bit fpc with 64bit lazarus? I am.
You need a recent fpc from svn though.
Steps for 64 bit lazarus.
1) download and install FPC 2.0 64 bit.
2) download and install svn fpc sources.
svn checkout
http://svn.freepascal.org/svn/fpc/trunk fpc
cd fpc
make all PP=ppcx64
su
make install PP=ppcx64
ln -sf /usr/local/lib/fpc/2.1.1/ppcx64 /usr/local/bin
this will install in /usr/local/lib/fpc/2.1.1
and create a link to the compiler in /usr/local/bin/
3) edit your /etc/fpc.cfg file
you should make sure the lines say:
-Fu/usr/local/lib/fpc/$fpcversion/units/$fpctarget
etc
5) get lazarus from svn
there are several bugs fixed in 64 bit lazarus in svn version so lazarus from svn is pratically a requirement

svn checkout
http://svn.freepascal.org/svn/lazarus/trunk lazarus
cd lazarus
make PP=ppcx64
then ./lazarus to start it
this is useful because it makes it easy to update from svn and recompile
("svn update" from inside the lazarus dir)
That's it now you have a working fpc/laz 64bit
For your libgdk_pixbuf problem eiither locate a 32bit package for your distro or you can copy the file from another pc to /usr/lib32/
