You can blame Lapck or COIN, but since we only have control on COIN, 
why not make it work even when nonstandard names are used ? What about
stripping the extension in the name of a library only if its name starts 
with "lib", for example.

This could happen with other libraries. Moreover, saying

is not particularly helpful. Unless the user is able to find the 
linking command in the sea of makefiles that comes with COIN, and unless 
he has some knowledge of make, I doubt he will be able to do that.
