[Typo3] phpMyAdmin ext install problems

[Franz Holzinger]

After installation of phpMyAdmin 0.1.0 in TYPO3 3.8 I still get error 
messages:


Warning: main(./lang/french-utf-8.inc.php): failed to open stream: No 
such file or directory in 
/var/www/html/typo3/ext/phpmyadmin/modsub/phpmyadmin-2.6.0-pl3/libraries/select_lang.lib.php 
on line 311

Fatal error: main(): Failed opening required 
'./lang/french-utf-8.inc.php' 
(include_path='.:/usr/lib/php/:/usr/share/pear/') in 
/var/www/html/typo3/ext/phpmyadmin/modsub/phpmyadmin-2.6.0-pl3/libraries/select_lang.lib.php 
on line 311


How to solve this?
