eval returns whatever the block of code returns. A block of code returns the return value of the last evaluated statement. use is a compile-time keyword, and at runtime, nothing happens in your evaled code, so it returns undef. Undef is false, so $@ is warned. But because nothing went wrong, $@ is empty, and warn warns "something's wrong".

Fix it like this: 

eval "...";
warn $@ if $@;

Or like this (make it return true): 

eval "...; 1;" or warn $@;

The first solution is better, imho.
