This is a rather silly general question but it's been bothering me for months.
I have a test machine running SLES 7 and there were so many times that I would want to recompile added features in the software (ie. recompile PHP to work with Oracle, add SASL support to Sendmail, update the GLIBC, etc, etc).
Does anyone know of, or have some sort of general strategy to make updates to the software when you aren't 100% sure how it is installed?
Any help would be greatly appreciated.
