>Description:
while installing, try the test:
/ports/devel/rlwrap/work/rlwrap-0.28
0 # src/rlwrap perl test/testclient
rlwrap: error: Could not open master pty: Input/output error
/ports/devel/rlwrap/work/rlwrap-0.28
1 #
i tried to find the bug through ktrace(1), it shows where rlwrap employs
openpty(3):
4198 rlwrap CALL open(0xbfbfdb10,0x8006,0)
4198 rlwrap NAMI "/dev/ptyp0"
4198 rlwrap RET open -1 errno 5 Input/output error
4198 rlwrap CALL open(0xbfbfdb10,0x8006,0)

4198 rlwrap CALL write(0x2,0xbfbfd900,0x3d)
4198 rlwrap GIO fd 2 wrote 61 bytes
"rlwrap: error: Could not open master pty: Input/output error
"
4198 rlwrap RET write 61/0x3d
the similar, but deprecated utility ports/editors/cle displays:

4755 cle RET readlink -1 errno 2 No such file or directory
4755 cle CALL issetugid
4755 cle RET issetugid 0
