Strange upgrade order.

[Erwan David]

I type port upgrade -R libpng

then first port tries to upgrade netpbm (and fails)
port upgrade -R libpng
--->  Fetching netpbm
--->  Attempting to fetch netpbm-10.26.44.tgz from http://downloads.sourceforge.net/netpbm
--->  Verifying checksum(s) for netpbm
--->  Extracting netpbm
--->  Applying patches to netpbm
--->  Configuring netpbm
--->  Building netpbm with target {}
rror: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_netpbm/work/netpbm-10.26.44" && gnumake  messages=yes " returned error 2

....

Then it upgrades libpng

Error: Unable to upgrade port: 1
--->  Fetching libpng
--->  Attempting to fetch libpng-1.2.22.tar.bz2 from http://downloads.sourceforge.net/libpng
--->  Verifying checksum(s) for libpng

--->  Installing libpng 1.2.22_0+darwin_8
--->  Activating libpng 1.2.22_0+darwin_8
--->  Cleaning libpng

and retries to upgrade netpbm

with same error

--->  Building netpbm with target {}
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_netpbm/work/netpbm-10.26.44" && gnumake  messages=yes " returned error 2

........


still tries...

Error: Unable to upgrade port: 1
--->  Building netpbm with target {}

and retries...

then tries to deactivate already deactivated version of libpng !

Error: Unable to upgrade port: 1
--->  Deactivating libpng 1.2.21_0+darwin_8
Error: Deactivating libpng 1.2.21_0 failed: Active version of libpng is not 1.2.21_0+darwin_8 but 1.2.22_0+darwin_8.


Why this strange behaviour ?

(PS: I keep the complete log of the session for who wants it)
