[ILUG-BOM] Help with library libmng.so.0 reqd

[Navin]

hi there guys,
i wanted to install opera ( the web browser) for 
linux and needed to upgrade qt for this purpose.
it seems qt 2.2 needs libmng.so.0, s i got this 
file (libmng.so.0) too. 
can anyone tell me where to place this lib file
so that the qt install sees it. i have tried copying
it to /lib , but i still get an error msg. plz hlp
bye
