Thanks to all who replied with suggestions last night. It turned out that my problem was related to the command
md5sum -c <AOO file>.tar.gz.md5 which is the specific md5sum command suggested on Apache's "How to verify the download <http://www.openoffice.org/download/checksums.html>" page. I had never used this command before. It was returning a specific error, "no properly formatted MD5 checksum lines found". After I posted my problem report, I ran this checksum command instead md5sum <AOO file>.tar.gz I verified the checksum manually by comparing the result with the md5sum provided on the download page. After that, I installed the file successfully. After doing a little research, I found more detailed <http://www.codejacked.com/using-md5sum-to-validate-the-integrity-of-downloaded-files/> information <http://www.cyberciti.biz/tips/howto-verify-integrity-of-the-tar-balls-with-md5sum-command.html> about how to verify the md5sum using md5sum -c. I still haven't managed to get it to work. I have an alternative, so that's okay, but I do wish I understood. Anyway, I thought someone else here might be interested in having the info, so here it is.
