no highlighted sourcecode in my doc

hello, I have put the flag --sourcecode on on the phpdoc command line and the tag @filesource in my page-level docblock phpDocumentor claims that 'ERROR in my.php on line 12: "filesource" tag is not available in PHP versions less than 4.3.0, tag ignored' But it does lie: my phpinfo() says my #!/usr/bin/php is 'PHP Version 4.3.1' I have tried with my other versions: /usr/bin/phpdoc with #!/usr/local/bin/php434 and #!/usr/local/bin/php435RC4 - Then there is another problem (and still no highlighted sources): 'Creating Directory doc-api/ Warning: mkdir(doc-api/): Permission denied in /usr/share/pear/PhpDocumentor/phpDocumentor/Converter.inc on line 4585' - With #!/usr/local/bin/php500b4 'Fatal error</b>: Cannot re-assign $this in /usr/share/pear/PhpDocumentor/phpDocumentor/ParserElements.inc on line 238' What would be the solution to get my highlighted sources? -- cheers
