Rotating a PDF file by n degrees, where n is not a multiple of 90

Question

The problem I am facing is as following. I have a source document, src.pdf.

I need to insert the contents of src.pdf into target.pdf, rotated by n degrees, where n is NOT a multiple of 90.

Any help would be appreciated, thanks.

EDIT 1:

PDF contains no annotations.

I can use any solution which relies on utilities, or write my own code, preferably in C#/Python/Ruby/Perl, but not limited to a language.

The platform is Windows Server 2008 R2, I prefer to stick to the existing server but Linux is also an option. Latest (stable) GhostScript and pdftk are already installed.

If a new language is not a problem, LateX could be an option. You can include a pdf as a figure in a tex file, and you will be able to use dedicated option like rescaling and rotating function. Then, compile it to obtain a new pdf. The very simple following code works for me :

\documentclass[a4paper]{article} 
\usepackage{graphicx}

\begin{document}

\includegraphics[scale=0.5,angle=10]{test.pdf} 

\end{document}

From this pdf:

I get this new one:

It will however need some manual ajustements to get exactly what you want...
