Bug 177677

"grep" seems to halt the configure of postgresql84-server [also the "install" of print/teTeX-base btw... and a third I've forgotten...] until moved, as shown by the log below.

halted (cntl-c, the above line terminates the configure until grep
is moved:)

#mmv /usr/local/bin/grep .

resumed ... configures normally as shown below.

Note the line after the halt above, continues with no pause at all
[As shown below, with grep moved out of the way.]
[Just enough of the configure sent to demonstrate the problem.]
