So true. :-) But if you want to become a power user it is very useful to study how this machinery works! > If you insist on building your own de-novo, then you are going to need > to crawl up that fairly steep learning curve.

Every journey begins with a first step. :-) Running ./configure --help can be helpful. It shows what the possible optio= ns and environment variables are. > Your first hurdle seems to be getting configure to choose consistent > settings. configure is expecting 'cc' on FreeBSD 10.x to actually be > clang -- which is what it usually is.

Usually, the configure from gnu autoconf expects gcc? I think that the defa= ult usage of clang is a feature of the ports tree. At least I often see a messa= ge like "patching auto** for FreeBSD 10" whizzing by when compiling a port. In general you have to set some environment variables for configure to use clang. For another app that I needed to compile outside of the ports tree I had to do something like this; env LDFLAGS=3D-L/usr/local/lib CPPFLAGS=3D-I/usr/local/include CC=3Dcla= ng \ CXX=3Dclang++ CFLAGS=3D-O2 ./configure <configure arguments for the app> gmake install You generally have to use =E2=80=98gmake=E2=80=99 instead of =E2=80=98make= =E2=80=99, since autotools Makefiles require extensions that only exist in gmake. In the best case the program doesn't require FreeBSD specific patches and t= he abovementioned commands work. But since the FreeBSD port of squid *does* contain FreeBSD specific patches (see in this case =E2=80=9C/usr/ports/www/squid/files/patch-*=E2=80=9D), you might need to ap= ply these as well to get the compile to work.
