It found rex_tre.so.

$ nm -D /usr/local/lib/libtre.so.4 | grep re_reganexec

I think you're out of date. Browsing the 0.8.0 sources I see in lib/Makefile.am:

libtre_la_LDFLAGS = -no-undefined -version-info 5:0:0 $(LDFLAGS)

This should produce a shared library with a basename like libtre.so.5 instead of 4.
