I'm noticing some random breakage with incremental builds, e.g. today in this incremental build (http://build.sagemath.org/#/builders/40/builds/59/steps/9/logs/stdio) the sage-conf package gets removed and then the installation crashed. I then re-ran exactly the same incremental build and it succeeded.
Possibly related, on OSX docbuild in incremental builds tends to die () with an [sagemath_doc_html-none] ImportError: cannot load Singular library from libSingular.so (b'dlopen(libSingular.so, 9): image not found') that then succeeds by re-runnnig. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
