During a testbuild of mozilla-1.7.3-18.EL4 in mock, the rebuild process stops with the following error: + desktop-file-install --vendor mozilla --dir /var/tmp/mozilla-root/usr/share/applications --add-category X-Fedora --add-categ ory Application --add-category Network /builddir/build/SOURCES/mozilla.desktop /var/tmp/rpm-tmp.59503: line 234: desktop-file-install: command not found error: Bad exit status from /var/tmp/rpm-tmp.59503 (%install) Adding desktop-file-utils to the BuildRequires list should fix this problem. Note: Even though I tested the SRPM from RHEL4, the same problem exists in rawhide. The issue is the same as with the thunderbird package: desktop-file-utils is already defined as a PreReq but it is needed for BuildPreReq as well.
Fixed in both RHEL4 and Rawhide.
