error: ./dist/configure line 40:conf19087.sh: No such file or directory

I get the error as above when trying to build Berkeley database version 4.5.20. I have unzipped the archive to /opt on UNIX. Please can anyone tell me what I need?

I do the followin开发者_StackOverflow社区g:

• Uncompress berkeley-db package in some directory. say in /opt
• cd to the build_unix directory
• ../dist/configure

When I run the last command it gives me the error as above. Does anyone know what I am missing here? Options? Another download?

Please make sure that you have correct file permissions for the distribution folder. Try chmod +w -R /opt/db-4.5.20
