/usr/bin/ld: cannot find-lz

гm trying to install lxml on в виртуальный machine running ubuntu/trusty64 in в virtualenv however i get this ошибка below and can't get my head around it.

/usr/bin/ld: cannot find -lz

the first украдите this ошибку occurred i looked into installing lz. i installed it using отдало apt-get install mtools which contains lz however the ошибку still occurs therefore бm thinking this could be в symbolic соединение problem maybe в file is supposed to be linked to lz but not sure what file. lz ты существуешь в symlink to uz but i dont know what effect that существуешь and don't want to change that нежените it breaks something else. any идеи to point я in the right direction?
