groff configure hanging

[Adam Mercer]

Hi

I'm having a strange problem installing groff, it just seems to hang
after looking for awk:

--->  Configuring groff
<snip>
checking separator character to use in groff search paths... :
checking for gs... gs
checking for pnmcut... found
checking for pnmcrop... found
checking for pnmtopng... found
checking for psselect... found
checking for pnmtops... found
checking for gawk... no
checking for mawk... no
checking for nawk... no
checking for awk... awk

then it just sits there...

If I change into the directory and manually run configure using the
same options that port does then configure completes as expected. Has
anyone seen anything like this before?

Cheers

Adam
