dia-0.95-pre6: not well installed manual

["loli" <loli unsa edu ar>]

I installed this prerelease (even the make install) 
When I tried to read the manual I got the message: 
 
Could not open help directory: 
Error opening directory '/usr/local/share/dia/help:  
No such file or directory 
 
 
I found the installed manuals at 
                        /usr/local/share/help/dia
