Could you tell us exactly what you're doing and what exactly does it <br>

Hmm, i don't see such string in the source code of scan-build, neither <br>
it looks like a standard Perl message.<br>
<br>
> don't install clang and related tools like scan-build in /usr/bin i <br>
am not able to generate reports ( HTML files )<br>
<br>
Could you provide the exact command and its exact output? Normally you <br>
don't care where is everything installed because you simply provide the <br>
path to the analyzer with `--use-analyzer`.<br>
