Yes, that's it. The post install script produces the error.
I found that /bin/sh is used in the script header. The Ubuntu has "dash" shell pointed by /bin/sh, not bash as it can be expected. I usually use another header for ensuring that script will run on bash:
!#/usr/bin/env bash
However just /bin/bash should work as well.
Anyway, I started post-install script with debug switch and got the following output:
kostap@shark:/opt/calibre$ sudo ./calibre_postinstall
+ export CALIBRE_CX_EXE=calibre_postinstall
+ CALIBRE_CX_EXE=calibre_postinstall
++ readlink -e ./calibre_postinstall
+ path=/home/sata0/opt/calibre/calibre_postinstall
++ dirname /home/sata0/opt/calibre/calibre_postinstall
+ base=/home/sata0/opt/calibre
+ loader=/home/sata0/opt/calibre/loader
+ export LD_LIBRARY_PATH=/home/sata0/opt/calibre:
+ LD_LIBRARY_PATH=/home/sata0/opt/calibre:
+ /home/sata0/opt/calibre/loader
./calibre_postinstall: line 7: 8979 Illegal instruction $loader "$@"

It works that way:
#!/bin/bash -x
export CALIBRE_CX_EXE=calibre_postinstall
path=`readlink -e $0`
base=`dirname $path`
loader=$base/loader
export LD_LIBRARY_PATH=$base:$LD_LIBRARY_PATH
exec $loader "$@"

But still "Illegal instruction" when loader is started.
So I tried to export all variables manually and start the loader using sudo:
kostap@shark:/opt/calibre$ sudo ./loader
Traceback (most recent call last):
File "/tmp/init.py", line 10, in <module>
File "/usr/lib/python2.6/locale.py", line 15, in <module>
File "/usr/lib/python2.6/functools.py", line 10, in <module>
ImportError: libpython2.6.so.1.0: cannot open shared object file: No such file or directory

That's right, I do not have Python 2.6 installation. My system is based on 2.5.
Is it really needed? I mean is it possible to re-build Calibre using pyton 2.5 and PyQt 4.3.3 instead of python 2.6 and PyQt 4.4.2 ?
I think then it will work on older systems too...
Unfortunately I cannot run the system upgrade - it will ruine all my cross-build toolchains...
Anyway, if it's impossible to adopt Calibre to older Ubuntu's, I will have to work with windows books management SW running on virtual machine (I hate this mode of operation, but sometimes there is no other choice)
