I just discovered something;

$ echo $OSFONTDIR
/usr/share/fonts/vista-fonts;/home/mohamed/.fonts;/media/sdb1/Fonts

$ pwd
/home/mohamed/.fonts/envy-code-r
$ ls -1
EnvyCodeRBold.ttf
EnvyCodeRItalic.ttf
EnvyCodeR.ttf
EnvyCodeRVSItalicAsBold.ttf
EnvyCodeRVS.ttf

$ mtxrun --script fonts --list "envy"
envy code r          Envy Code R          EnvyCodeR.ttf
envy code r bold     Envy Code R Bold     EnvyCodeRBold.ttf
envy code r italic   Envy Code R Italic   EnvyCodeRItalic.ttf
envy code r vs       Envy Code R VS       EnvyCodeRVS.ttf
envy code r vs bold  Envy Code R VS Bold  EnvyCodeRVSItalicAsBold.ttf

# similar error to the previous one, even though mtxrun finds it, luatex 
doesn't. If I copy the fonts over to the working directory, the file seems 
to compile fine (http://pastebin.com/m5272c619 or attached). $ texexec
