By "any machine", do you mean that you want to copy a whole sub- 
directory
tree from one place to another?

Then you could use "hard links" ( ln <source> <target>) instead of
symbolic links  ( ln -s <source> <target>)

Or when you make an archive  tar -h   follows symbolic links
and includes the file itself, rather than the link.

If the HTML directory is a subdirectory of where the source is located,
this may need to be  \graphicspath{{./mypics/}{../mypics/}} .

Or have a symbolic link to the directory within the HTML directory.

Either of these should ensure that the  $COPY_GRAPHICS=1   branch
of the coding in   graphics-support.perl  has the correct directories
listed in the  $GRAPHICS_PATH  variable.

Try the above suggestions.
