It does not:

$ port deps pcre
Full Name: pcre @8.33_0
Build Dependencies:   autoconf, automake, libtool
Library Dependencies: bzip2, libedit, zlib

It does not; it has clang. But that’s ok; gcc is not required.

pcre was already successfully installed.

Other ports you already had installed were determined to be broken.

gcc42 does not build on Leopard or later. You should uninstall it.

How did you get it installed in the first place? Presumably you installed it on an older OS, then upgraded to Mavericks? You should uninstall and reinstall all ports after doing so. There are other steps you should do too, described here:
