Description:
------------
having the absolute path will make the SVG file machine specific.  Not all machines will have the font in the same location.

The line 761 in SVG.php needs to be changed.  Easiest fix would be to enclose this->_font['name'] in the basename function

Expected result:
----------------
<text x="0" y="0" style="font-family:verdana.ttf;font-size:8px;fill:rgb(0,0,0);text-anchor:end;">500</text>

Actual result:
--------------
<text x="0" y="0" style="font-family:/abosolute/path/to/font/on/linux/verdana.ttf;font-size:8px;fill:rgb(0,0,0);text-anchor:end;">500</text>

I take that back about basename.  It isn't enitrely correct.  I would recommend pathinfo and use the 'filename' element.  That way, the extension will be stripped off.  The presense of the extension could cause a problem when a machine doens't have an OpenType version of a TrueType font and vice-versa, and other combinations etc...

Are you able to provide a small executable test case to demonstrate this bug?
