It isn't in the product shiplist (I don't know why). This means it won't be in the Aviage release, but here is a link to
 the foundry 27 release that should still work: 
http://community.qnx.com/integration/viewvc/viewvc.cgi/trunk/services/qdb/cldr/?root=multimedia&system=exsy1001

If you check out the multimedia source following the documentation in the multimedia project, you should be able to build it.

No. It is based on a standard UCA (Unicode Collation Algorithm). http://www.unicode.org/reports/tr10/#Introduction

It doesn't use ICU. But using the sourcecode on foundry 27 (even though it is based on our trunk, QDB/Sqlite has not has
 any big changes since Aviage 1.2) you could build libqdb_cldr yourself, or use it as a base for a different collation 
algorithm.

Sorry, just further information. Maybe you don't care about libqdb_cldr.so at all, you just want ICU support in SQLite 
to do things like case insensitive matching, etc. You can also do this by building the ICU library for QNX. Then you can
 download and build an ICU extension from the sqlite.org website:
http://www.sqlite.org/cvstrac/dir?d=sqlite/ext/icu

Then, check out the sqlite3 source code from the foundry 27 Multimedia project and rebuild ti with "SQLITE_ENABLE_ICU" 
defined.
