QUEX_PATH проблема при использовании токенизатора

Я пытаюсь установить trainable-tokenizer. Я установил все зависимости в соответствии с README. это обучаемый токенизатор https://github.com/jirkamarsik/trainable-tokenizer. я установил quex.deb с помощью установщика из quex.org, который является зависимостью для trainable-tokenizer.

когда я пытаюсь сделать sudo make install я получаю следующую ошибку

ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ sudo make install
[  6%] Building FeaturesReader with quex
Environment variable QUEX_PATH has not been defined.
error: environment variable 'QUEX_PATH' is not defined.
error: your system is 'posix'.
error: if you are using bash-shell, append the following line
error: to your '~/.bashrc' file:
error:
error: export QUEX_PATH=directory-where-quex-has-been-installed
make[2]: *** [quex_files/trtok_read_features_FeaturesReader] Error 255
make[1]: *** [CMakeFiles/trtok.dir/all] Error 2
make: *** [all] Error 2

но я уже настроил QUEX_PATH.

ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ echo $QUEX_PATH
/opt/quex/quex-0.65.4/
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ ll /opt/quex/quex-0.65.4/

я также добавил export QUEX_PATH=/opt/quex/quex-0.65.4/ к .bashrc

ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ vim ~/.bashrc
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ echo $QUEX_PATH
/opt/quex/quex-0.65.4/
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ sudo make install

но все равно я получаю ту же ошибку.
