netpbm 10.64.01 causes groff configure to hang

[benjamin.weaver@…]

I am trying to upgrade groff @1.22.2_1 from Lion to Mountain Lion. During the configuration stage, the configure command hangs when it reaches this line (line number 10445) of the configure file:

    if echo P2 2 2 255 0 1 2 0 | pnmtops -nosetpage > /dev/null 2>&1 ; then

OS: 10.8.5/Mountain Lion Xcode: 5.0 (5A1413)

When I download the groff tarball and run configure manually, it does not hang on this line.

I tried moving the command out of the if clause like this:

#    if echo P2 2 2 255 0 1 2 0 | pnmtops -nosetpage > /dev/null 2>&1 ; then
    echo P2 2 2 255 0 1 2 0 | pnmtops -nosetpage > /dev/null 2>&1
    if test $? = 0 ; then

but it still stalled when it hit the pipe. Finally I just did this:

#    if echo P2 2 2 255 0 1 2 0 | pnmtops -nosetpage > /dev/null 2>&1 ; then
#    echo P2 2 2 255 0 1 2 0 | pnmtops -nosetpage > /dev/null 2>&1
    if /usr/bin/true ; then

and the port configured and compiled successfully.

#40797 says that this happens on Mavericks, too.

Groff configure hangs for me in the same way on Mac OS X 10.6.8. The problem appeared to start after the upgrade of netpbm to 10.64.01; groff configure did not hang with netpbm 10.62.09.

The fix mentioned in #40797 allows me to build groff successfully.

I've emailed the developer of netpbm to ask if he understands why pnmtops is hanging here.

[ryandesign (Ryan Carsten Schmidt)]

Pending a proper fix, removed the test for now in r112336, since we know what version of netpbm is in MacPorts and whether or not its pnmtops supports -nosetpage (it does).

[ryandesign (Ryan Carsten Schmidt)]

The developer of netpbm identified and fixed the problem in version 10.64.02 to which I updated our port in r113202 so I reverted the workaround from the groff port in r113203.
