Unable to load library icui18n "Cannot load library icui18n: (ld.so.1: qtdemo: fatal: icui18n: open failed: No such file or directory)"

1. After building qt, I run "qtdemo" as below:

$ ./qtdemo
Unable to load library icui18n "Cannot load library icui18n: (ld.so.1: qtdemo: fatal: icui18n: open failed: No such file or directory)"
$

2. How I built icu on solaris x86?

504 export LD_OPTIONS='-R/opt/NGRS/contrib/icu/lib'
506 gunzip icu4c-4_8_1_1-src.gz
508 mv icu4c-4_8_1_1-src icu4c-4_8_1_1-src.tar
512 tar xvf icu4c-4_8_1_1-src.tar
516 less readme.html
521 cd source/
523 cd common/unicode/
524 less uversion.h
525 less utypes.h
529 chmod +x runConfigureICU configure install-sh
538 ../source/runConfigureICU --help
539 ../source/runConfigureICU SolarisX86 --with-data-packaging=archive --prefix=/opt/NGRS/contrib/icu

3. How I built qt on solaris x86?

I linked to icu lib and icu header files by brute force.

503 export LD_OPTIONS='-R/opt/NGRS/contrib/qt-4.8.5/lib'
504 export LD_LIBRARY_PATH=/opt/NGRS/contrib/icu/lib:$LD_LIBRARY_PATH
505 echo $LD_LIBRARY_PATH
506 ./configure -prefix /opt/NGRS/contrib/qt-4.8.5 -fast -webkit -nomake tutorial -L /opt/NGRS/contrib/icu/lib -I /opt/NGRS/contrib/icu/include -nomake examples
507 gmake
508 gmake install

4. Questions?

What is the path when qt is looking for icu lib (actually dynamically load within file "tools/qlocale_icu.cpp")?

Which version of hearder files (different versions matter) qt included into ?

How we hard coded the correct path for icu lib and icu header file include paths?

What is the correct version for icu for qt-4.8.5 or later?

How did you recommend us to build icu?

Can we not use icu lib if we still have to use webkit components?
