I'm having the following error when trying to build Gretl from sources: * make -j2* " ./builddate make -C po build.h is current make -C xdg make[1]: Entering directory `/home/acer/gretl-git/po' make[1]: Entering directory `/home/acer/gretl-git/xdg' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/home/acer/gretl-git/xdg' /usr/bin/msgmerge --update bg.po gretl.pot /usr/bin/msgmerge --update ca.po gretl.pot ............................................................................................................................................................................................................................................................................................................................................................................................................... done. make -C lib ............................................................................................................................................................................................................................................................................................................................................................................................................... done. /usr/bin/msgmerge --update cs.po gretl.pot make[1]: Entering directory `/home/acer/gretl-git/lib' make[1]: *** No rule to make target `../lib/src/asa047_mod.c', needed by `gretl_bfgs.lo'.

Until now the builds were ok on this machine (Ubuntu 14.04), and the configure command doesn't show any errors.
