test for file existance fails if its a symlink

[Jason Lewis]

Hi,

In rubber, if you try to compile a document that has the graphicx package in it with symlinks, you get warnings (incorrrectly)

jason@debian:~/catalogue$ ls -l green_pen.jpg link_green_pen.jpg /tmp/LaTeXCatalogueSymlinks/gp.jpg
-rwxr-xr-x 1 jason src 185220 Mar 24 12:27 green_pen.jpg
lrwxrwxrwx 1 jason jason 13 Mar 28 16:22 link_green_pen.jpg -> green_pen.jpg
lrwxrwxrwx 1 jason jason 35 Mar 29 12:06 /tmp/LaTeXCatalogueSymlinks/gp.jpg -> /home/jason/catalogue/green_pen.jpg

\documentclass{report}
\usepackage{graphicx}
\begin{document}

                  \includegraphics[width=12cm,height=2.9cm,keepaspectratio=true]{green_pen.jpg}
                  \includegraphics[width=12cm,height=2.9cm,keepaspectratio=true]{link_green_pen.jpg}
                  \includegraphics[width=12cm,height=2.9cm,keepaspectratio=true]{/tmp/LaTeXCatalogueSymlinks/gp.jpg}
\end{document}

compiling this yields the following:

jason@debian:~/catalogue$ rubber -f -d test-rubber.tex
test-rubber.tex:7: graphics `/tmp/LaTeXCatalogueSymlinks/gp.jpg' not found
compiling test-rubber.tex...

jason@debian:~/catalogue$ rubber --version
Rubber version: 1.1
module path: /usr/share/rubber

I should add that this error seems to be when including a file, that is a symlink, and the symlink itself is not located in the same directory as the latex file being compiled.

the resulting document does howerver correctly include the image
