Installed .sty with tlmgr but latex can't find it

I have installed Tex live 2013 Version 3.1415926 and I want to install the package mdframed.

My first try was to enter in the terminal

tlmgr install mdframed


but the terminal responded to me that I am not allowed to do that. When I entered

sudo tlmgr install mdframed


sudo -i


added the tex path in /root/.bashrc and finally entered

tlmgr install mdframed
tlmgr update mdframed


and it worked! But if I compile my latex file the error

! LaTeX Error: File mdframed.sty' not found.


remains. Any Idea how to solve it?

EDIT: Output of

kpsewhich mdframed.sty


is

/usr/local/texlive/2013/texmf-dist/tex/latex/mdframed/mdframed.sty

Do you work under Unix? Maybe you have different paths. Did you try compiling the file from the terminal? Please show us the output in the terminal of kpsewhich mdframed.sty. –  Marco Daniel Sep 8 '13 at 12:39
Yes I work under Unix. Thank you for the hint to try to compile in terminal - that did work. I use texmaker but it does not seem to work there. The command line for Pdflatex is pdflatex -synctex=1 -interaction=nonstopmode %.tex –  Adam Sep 8 '13 at 16:49
I just noticed that in the log file from texmaker the first line is This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)` instead of Tex Live 2013. Can you tell me how to change that? –  Adam Sep 8 '13 at 16:58
Take a look at How to install “vanilla” TeXLive on Debian or Ubuntu?: the bit about finalising installation covers paths. –  Joseph Wright Sep 8 '13 at 17:00
