I'm trying to push the latest version 0.5 to Pentoo and facing this problem.
I have installed the tool using the standard "make install" function and got the following structure:

/usr/bin/whatweb
/usr/share/whatweb/*
```
However, it fails to start with the following message:
```
/usr/lib64/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- lib/whatweb (LoadError)
        from /usr/lib64/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from /usr/bin/whatweb:37:in `<main>'
```


FYI: the previous version used to have the following loader:
```
## set up load paths - must be before loading lib/ files
# add the directory of the file currently being executed to the load path
$LOAD_PATH.unshift(File.expand_path(File.dirname(__FILE__))) unless
    $:.include?(File.dirname(__FILE__)) || $LOAD_PATH.include?(File.expand_path(File.dirname(__FILE__)))
$LOAD_PATH << "/usr/share/whatweb/"
```

I think symlink should be supported as in previous version too. Because I just link whatweb to my bin folder instead of run make install.
There is a PR for this issue #282

commented

yes, I guess make install should just create a symlink after you patch. That would be the proper fix.

Thanks for the help @blshkv and @sytranvn

something is broken. Please re-open this bug

ok, found it. You have to make sure that BINPATH exists before linking the binary:
