ltmain.sh not found

[Willem Offermans]

Dear FreeBSD friends,

Almost every third port update ends with ``configure.ac:6: error: required file './ltmain.sh' not found``.
See output below!

I can copy ltmain manually: cp -p /usr/local/share/libtool/build-aux/ltmain.sh ., but this is quite
cumbersome.

Does anyone know a more elegant solution?


Erroneous example:
