I am trying to install a local package draftwatermark to override an out-of-date version of the package, by applying the answer in How to have local package override default package .
I have placed the files draftwatermark.ins and draftwatermark.dtx from http://www.ctan.org/tex-archive/macros/latex/contrib/draftwatermark into the directory
~/texmf/tex/latex/draftwatermark
Unfortunately, based on version number, pdflatex is still using the global version. Therefore, I am wondering how I can interrogate pdflatex for its package search path, and modify it without root privileges.
draftwatermarkon CTAN; while the package has version 1.1, it still advertises itself as version 1.0; trykpsewhich draftwatermark.styfrom the command line to see what path is used for loading it. However, you should first unpackdraftwatermark.styby running pdflatex ondraftwatermark.ins– egreg Jan 31 '13 at 00:18
