make separator error
 

Trying to install Tk for Perl, using instructions in INSTALL file from Tk800.025
I ran perl Makefile.PL OK
Then ran make, and got this error message:
# make
Makefile:95: *** missing separator. Stop.

Makefile has these lines near 95:

93 installhtml1dir=''
94 installhtml3dir=''
95 installman1
96 INSTALLSITEBIN = /usr
97 INSTALLVENDORBIN = /usr/bin'

What does this mean?

Any help appreciated,
Rob
