Create a file in /usr/lib/lazarus/1.0.10/packager/globallinks named leakview.lpk.

 Write these lines on that file..

The xml file is modified ,The "<" symbol replaced by less then and ">" is replaced by greater than

However the xml file is at 

http://svn.freepascal.org/svn/lazarus/trunk/components/leakview/leakview.lpk


Then go the /usr/lib/lazarus/1.0.10/packager/globallinks directory and chek if there is a file called leakview.lpl,open the file in nano and see if this line is there

$(LazarusDir)/components/leakview/leakview.lpk

restart lazarus and you are done
