I believe the error you are seeing (which I was able to duplicate here) is
mostly a warning.
I also saw something regarding service policy not configured on
virtual-template.

However, I was able to form a bundle with the following configs.

R1:

interface Serial0/1
 no ip address
 encapsulation frame-relay
 clock rate 2000000
 frame-relay interface-dlci 301 ppp Virtual-Template2
 frame-relay intf-type dce

interface Serial1/0
 no ip address
 encapsulation frame-relay
 frame-relay interface-dlci 103 ppp Virtual-Template1

interface Virtual-Template1
 no ip address
 ppp multilink
 multilink-group 1

interface Virtual-Template2
 no ip address
 ppp multilink
 multilink-group 1

interface Multilink1
 ip address 172.16.1.1 255.255.255.0
 ppp multilink
 multilink-group 1

R1#sh ppp multilink

Multilink1, bundle name is R3
  Bundle up for 00:11:07
  0 lost fragments, 0 reordered, 0 unassigned
  0 discarded, 0 lost received, 1/255 load
  0xE received sequence, 0xE sent sequence
  Member links: 2 active, 2 inactive (max not set, min not set)
    Vi1, since 00:11:07, last rcvd seq 00000C
    Vi2, since 00:07:17, last rcvd seq 00000D

R3:

interface Serial0/0
 no ip address
 encapsulation frame-relay
 frame-relay interface-dlci 301 ppp Virtual-Template2

interface Serial0/1
 no ip address
 encapsulation frame-relay
 clock rate 2000000
 frame-relay interface-dlci 103 ppp Virtual-Template1
 frame-relay intf-type dce

interface Virtual-Template1
 no ip address
 ppp multilink
 ppp multilink group 1
!
interface Virtual-Template2
 no ip address
 ppp multilink
 ppp multilink group 1

interface Multilink1
 ip address 172.16.1.3 255.255.255.0
 ppp multilink
 ppp multilink group 1

R3#sh ppp multilink

Multilink1, bundle name is R1
  Bundle up for 00:10:35, 1/255 load
  Receive buffer limit 24384 bytes, frag timeout 1000 ms
    0/0 fragments/bytes in reassembly list
    0 lost fragments, 0 reordered
    0/0 discarded fragments/bytes, 0 lost received

  Member links: 2 active, 2 inactive (max not set, min not set)
    Vi1, since 00:14:24
    Vi3, since 00:06:44

Verified traffic is balanced

R1#ping 172.16.1.3 repeat 100000000 size 1250

R1#sh int | i Serial|rate
  Serial0/1 is up, line protocol is up
  5 minute input rate 79000 bits/sec, 48 packets/sec
  5 minute output rate 79000 bits/sec, 48 packets/sec
  Serial1/0 is up, line protocol is up
  Hardware is QUICC Serial
  Queueing strategy: dual fifo
  5 minute input rate 79000 bits/sec, 48 packets/sec
  5 minute output rate 79000 bits/sec, 48 packets/se
