I think the problem is in the following lines in makefile:

install -d -m 644 $(KDE_LOCALE)/de/LC_MESSAGES
install -d -m 644 $(KDE_LOCALE)/ca/LC_MESSAGES
install -d -m 644 $(KDE_LOCALE)/es/LC_MESSAGES
install -d -m 644 $(KDE_LOCALE)/pt_BR/LC_MESSAGES

It seems it tries to install something in KDE directory
