net-misc/unison-2.27.57-r1 only compiles with ocamlopt being installed, which depends on the USE flag ocamlopt in dev-lang/ocaml. See this error message, lacking any hint to the USE flag: >>> Compiling source in /var/tmp/portage/net-misc/unison-2.27.57-r1/work/unison-2.27.57 ... ocamlc -o mkProjectInfo mkProjectInfo.ml ./mkProjectInfo > Makefile.ProjectInfo UISTYLE = text Building for Unix NATIVE = true THREADS = false STATIC = false OSTYPE = OSARCH = echo 'let myName = "'unison'";;' > ubase/projectInfo.ml echo 'let myVersion = "'2.27.57'";;' >> ubase/projectInfo.ml echo 'let myMajorVersion = "'2.27'";;' >> ubase/projectInfo.ml ocamlopt: ubase/projectInfo.ml ---> ubase/projectInfo.cmx ocamlopt -I lwt -I ubase -c /var/tmp/portage/net-misc/unison-2.27.57-r1/work/unison-2.27.57/ubase/projectInfo.ml make: ocamlopt: Kommando nicht gefunden make: *** [ubase/projectInfo.cmx] Fehler 127 * * ERROR: net-misc/unison-2.27.57-r1 failed. * Call stack: * ebuild.sh, line 49: Called src_compile Reproducible: Always
