If you > upgraded the dependant binaries, wouldn't you get the same effect? I see compiling from source as a way to reduce and/or alter dependencies, and number/size of installed files. One drawback of using pkg_add to install a binary package is that it requires unnecessary upgrade of dependencies. If a package to be installed requires x-1.2.3 but x-1.2.2_p9 is already installed AND there will be no problem of using x-1.2.2_p9, x-1.2.3 will be installed regardless in addition to x-1.2.2_p9, quite possibly overwriting the files. The packages are almost never suitable for me even though i do not run servers other than for personal needs. > One certain drawback of compiling from source is the compilation > time.

BTW, your concerns have had been dealt w/ in past, at least once this year. - Parv --
