Calling checkloaded with wrong parameter?

If I load a library with relative path, e.g `./sample-library.so`, the checkloaded function fails.

In the source code you're looking for the relative path, 

```
if(checkloaded(target, libname))
```

Why not look for canonical path?  The following code fixes the problem:

```
if(checkloaded(target, libPath))
```
