------------------------------------------------+-------------------
 First and foremost, apologies if this is repeating another ticket, but I
 have searched and can not find anything relevant.

 I am not certain exactly when this problem started but I believe it was
 with Macports 2.4.

 My system: Mac OS Sierra, 10.12.3, Xcode 8.2.1, Macports 2.4.0, in more
 detail:
 {{{
 $ uname -a
 Darwin ma018012.ads.eso.org 16.4.0 Darwin Kernel Version 16.4.0: Thu Dec
 22 22:53:21 PST 2016; root:xnu-3789.41.3~3/RELEASE_X86_64 x86_64
 $ port version
 Version: 2.4.0
 $ xcodebuild -version
 Xcode 8.2.1
 Build version 8C1002
 }}}

 I used to be able, prior to version 2.4 of MacPorts, to install a port
 with the following command:
 {{{
 $ sudo port install ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-
 fposs.bz2
 }}}

 Where the contents of the file flames-fposs.bz2 are simply:
 {{{
 $ tar -tf flames-fposs.bz2
 flames-fposs/Portfile
 }}}

 But since version 2.4, I get the following error when attempting to
 install a port via a specified URL:

 {{{
 $ sudo port install ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-
 fposs.bz2
 --->  Fetching port ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-
 fposs.bz2
 Can't map the URL 'ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-
 fposs.bz2' to a port description file ("couldn't change working directory
 to "/opt/local/var/macports/portdirs/flames-fposs": no such file or
 directory").
 Please verify that the directory and portfile syntax are correct.
 Error: Can't open URL 'ftp://ftp.eso.org/pub/usg/fposs/P99/macports
 /flames-fposs.bz2' as a port
 Error: Improper expression syntax while processing parameters
 }}}

 If I manually extract the file into /opt/local/var/macports/portdirs/ then
 it works:
 {{{
 $ ftp ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-fposs.bz2
 $ sudo tar -C /opt/local/var/macports/portdirs/ -xvf flames-fposs.bz2
 x flames-fposs/Portfile
 $ sudo port install ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-
 fposs.bz2
 --->  Fetching port ftp://ftp.eso.org/pub/usg/fposs/P99/macports/flames-
 fposs.bz2
 --->  Computing dependencies for flames-fposs
 --->  Cleaning flames-fposs
 --->  Scanning binaries for linking errors
 --->  No broken files found.
 }}}

 This has the problem that if a previous version of this port was installed
 (e.g. ftp://ftp.eso.org/pub/usg/fposs/P98/macports/flames-fposs.bz2), and
 thus the older version of the Portfile already exists in
 /opt/local/var/macports/portdirs/flames-fposs, then the older version gets
 installed rather than the newer one.

 So it seems that:
 1) for extraction, MacPorts is assuming that all ports specified as remote
 URLs are binary packages, and this it is not handling correctly Portfile
 distribution via this mechanism
 2) It is nonetheless still handling "correctly" processing the Portfile if
 it happens to already exist, or if the user "manually installs" it into
 /opt/local/var/macports/portdirs/.

 Is is a bug? Or a new feature?

 Many thanks in advance.

 Cheers

 P.S. Yes I know I should just put this package in a proper repository
 somewhere, that's coming, but it's... complicated...
