The installation was smooth with no errors. However, when writing a simple example code that calls the QAG integration routine from the library I get the following error: {{{ Undefined symbols for architecture x86_64: ""_slamch_"", referenced from: _r1mach_ in libslatec.a(r1mach.o) ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status }}} slamch is begin referred from r1mach - which is a routine that deals with machine constants I think. This is an unexpected error given that the dependencies should have been taken care of by MacPorts. I’m using Mavericks 10.9.5 on in Intel laptop if that helps. Many thanks.
