Hoi Ed, for sunos, the following recipe worked for me: newrel -t analysis-24 vub cd vub/ srtpath 16.0.3 SunOS58 addpkg RecoilAnalysis addpkg VubAnalysis gmake installdirs cd RecoilAnalysis gmake -f Makefile lib cd ../VubAnalysis gmake -f Makefile b2u You'll need the HEAD of cvs, in addition to the modified SunOS if statements there was also an ambiguity for a not-used pow() call. I commented the problem. Cheers, --U.
