I tried to build textproc/unroff on IRIX 5.3 (mips). I got:

...
===> Extracting for unroff-1.0.2
===> Required package elk>=3.0.2: NOT found
===> Verifying reinstall for ../../lang/elk
===> elk-3.0.3 is not available for IRIX-5.3-mipseb
===> Returning to build of unroff-1.0.2
===> Required installed package patch>=2.2: patch-2.5.4nb2 found
===> Patching for unroff-1.0.2
...

shouldn't it stop when it cannot build a required package?
BTW, as a consequence compiling later fails due to a missing include
file.
