I found the issue. Very odd. For some reason, when I last built PCRE, it did not create symlinks for some of the files. These were missing:
/usr/local/lib/libpcre.so -> libpcre.so.0.0.1
lrwxrwxrwx 1 root other 16 Jul 17 16:55 /usr/local/lib/libpcre.so.0 -> libpcre.so.0.0.1
-rwxr-xr-x 1 root other 433948 Jul 12 2006 /usr/local/lib/libpcreposix.so -> libpcreposix.so.0.0.0
lrwxrwxrwx 1 root other 21 Jul 17 16:56 /usr/local/lib/libpcreposix.so.0 -> libpcreposix.so.0.0.0
Once those were in place, the linker added in libpcre as well as libgcc as expected. Everything's working again. :) By the way, I was doing this so I could add a WIKI button to alert pages, which when clicked, does an auto-search in our internal wiki using that hostname and service as the keywords. Works great! One more thing I need to document and upload.
