Differences between mock and koji?

Hello, I have a package that builds fine in a fresh rawhide mock chroot and not in a koji build. Is there any difference between the two? Here is the error in Koji: + make -j5 LIBPATH=/usr/lib64 -f makefile docs rm -f doc/crypt.pdf *.dvi *.log *.aux *.toc *.idx *.ilg *.ind *.out echo "hello" > crypt.ind latex crypt > /dev/null kpathsea: Running mktexfmt latex.fmt make: *** [docs] Error 1 RPM build errors: error: Bad exit status from /var/tmp/rpm-tmp.5TWg4P (%build) Bad exit status from /var/tmp/rpm-tmp.5TWg4P (%build) And here is the same step in mock: DEBUG: + make -j4 LIBPATH=/usr/lib64 -f makefile docs DEBUG: rm -f doc/crypt.pdf *.dvi *.log *.aux *.toc *.idx *.ilg *.ind *.out DEBUG: echo "hello" > crypt.ind DEBUG: latex crypt > /dev/null DEBUG: latex crypt > /dev/null DEBUG: makeindex crypt.idx > /dev/null DEBUG: This is makeindex, version 2.15 [TeX Live 2013] (kpathsea + Thai support).
