on installation the m4-1.4.10nb2 package (from source or binary makes no difference) only /usr/pkg-bin-gm4 is installed,
 but not /usr/pkg/bin/m4.

is there any reason for that?

background is, that security/beecrypt needs m4. Otherwise it would build, but the resulting libraries miss several 
implementation. which unfortuanitly is first detected when using the libraries ;-)

my current quck solution is a symbolic link /usr/pkg/bin/m4 --> /usr/pkg/bin/gm4.

bit i'm very suprised about that point and think there must be something else. m4 is not that unusual in my opinion.
