Well, I should've been more explicit. The server works (MySQL, Apache, etc) except for IPSConfig. The installation can't get past the error message,
"relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC"
It appears from the advice in your link above that zlib should be recompiled with the --shared option to work around this problem. I just want to be sure I'm not going to break anything else in the installation when it's recompiled. Or at least I'd like to have some idea of what will break so I have some clue what to fix.
