Virtuoso-7 fail to build in Mac OS 10.14

[lukewmo (Luke Mo)]

I want to build okular, but it stopped at the failure of virtuoso-7. The Xcode is 10.1, and it is properly installed and complete. The error message is the following:

---> Fetching distfiles for virtuoso-7
---> Attempting to fetch virtuoso-opensource-7.2.5.tar.gz from
https://distfiles.macports.org/virtuoso-7
---> Verifying checksums for virtuoso-7
---> Extracting virtuoso-7
---> Configuring virtuoso-7
Some antivirus software can cause the virtuoso build to hang
indefinitely. If you have any antivirus software installed,
please disable it while building virtuoso; it can be re-enabled
after virtuoso has been installed.

This happened only on my MacBook Pro.

I installed virtuoso-7 successfully on two IMacs without any difficulty. they are also running with OS 10.14 and Xcode 10.1.
