Sysstat make: o: Command not found

I was compiling sysstat for Centos 6 with a --prefix option, but kept getting a set of errors like:

make: o: Command not found make: [nls/sk.gmo] Error 127 (ignored) o nls/sr.gmo nls/sr.po make: o: Command not found make: [nls/sr.gmo] Error 127 (ignored) o nls/sv.gmo nls/sv.po make: o: Command not found make: [nls/sv.gmo] Error 127 (ignored) o nls/uk.gmo nls/uk.po make: o: Command not found make: [nls/uk.gmo] Error 127 (ignored) o nls/vi.gmo nls/vi.po make: o: Command not found make: [nls/vi.gmo] Error 127 (ignored) o nls/zh_CN.gmo nls/zh_CN.po make: o: Command not found make: [nls/zh_CN.gmo] Error 127 (ignored) o nls/zh_TW.gmo nls/zh_TW.po make: o: Command not found make: [nls/zh_TW.gmo] Error 127 (ignored) make distclean

Which really reduces to just "make: o: Command not found" repeated for lots of objects. What gives? I tried playing with CXX=g++ stuff, but it turned out the problem was only with the NLS support, which I disabled in the ./configure step, and the compile worked (note: still won't 'make test'). Successfull line:

./configure --prefix=/opt/recon/dcm/platforms/CENTOS6 --disable-documentation --disable-stripping --disable-sensors --disable-nls

And, voila, it works.
