OMG. This is utter crap:
~/felix>otool -L
/usr/local/lib/felix/felix-1.1.7dev/lib/rtl/libflx_async_dynamic.dylib
/usr/local/lib/felix/felix-1.1.7dev/lib/rtl/libflx_async_dynamic.dylib:
build/release/lib/rtl/libflx_async_dynamic.dylib (compatibility version
0.0.0, current version 0.0.0)

version 0.0.0, current version 0.0.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current
version 7.9.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 125.2.11)
in other words we have installed libraries that cannot work because they depend
on
the build directory?? GRRRRRR.

The question is: why does this run??????? It's just rubbish.
build/release has been deleted.

So the documentation is rubbish.
/usr/local/lib/felix/felix-1.1.7dev/bin/flx_arun:
build/release/lib/rtl/libfaio_dynamic.dylib (compatibility version
0.0.0, current version 0.0.0)

~/felix>flx test/regress/rt/re2-01
Captures = 2
true
varray(Hello, , H)
So re2 works.
~/felix>DYLD_LIBRARY_PATH=/usr/local/lib/felix/felix-1.1.7dev/lib/rtl
/usr/local/lib/felix/felix-1.1.7dev/bin/flx_run test/regress/rt/re2-01.dylib
Captures = 2
true
varray(Hello, , H)
Similarly, the webserver "just works" if the DYLD_LIBRARY_PATH is set as above.
Contrary to the documentation.
