quests not working... (Ubuntu)

[Arex]

I am using Ubuntu 6.06, mysql 5.0, and latest server code, latest DB code, and latest quest package, and all works ok when i delete quests folder, but when quest folder is in his place, i get a error and zone crashes. it happens me since eqemu server code 0.7.0 - 944 aprox. and i am getting a error when compiling, using 'make clean' and 'make' (but this error let me continue compiling):

/bin/sh: -D_REENTRANT: not found


any idea? I wasnt getting that error when quests was working
